vinagre crashed with SIGSEGV in setcontext()

What version of gtk-vnc are you using?

Anthony, you can view that in Dependencies.txt:

libgtk-vnc-1.0-0 0.3.1-1

Can you provide more details on the steps to reproduce this problem? How many servers were you connecting to, what types of servers were they (RealVNC, Vino, etc.), what type of authentication where the servers configured to use?

I can reliably reproduce this crash while using vinagre to connect to an Adder (a hardware VGA->VNC unit) which works correctly with vncviewer.
The authentication it offers is:
 CConnection: Server offers security type RA2(5)
 CConnection: Server offers security type RA2ne(6)
 CConnection: Server offers security type VncAuth(2)
vncviewer chooses VncAuth(2).

Please let me know if you need more information.

Could you try with vinagre 0.4? There's a deb at http://emilio.pozuelo.org/~deb/vinagre_0.4-1_i386.deb, and the package will be synced soonish to Hardy (once it's newed in Debian). Alternatively the sources are in the same directory, in case you have another arch or want to build the package yourself.

Also, could you compile gtk-vnc with --enable-debug flag ? With this option, you can obtain detailed output of the connection, if running vinagre in a terminal.

Please, do that and paste here the output you see in terminal.

Also, it would help if you could use debug information in your build. (something like running: export CFLAGS="-g -O0" before buiding gtk-vnc and vinagre)

I just reproduced this bug trying to connect to a vino server protected by a password. I viewed the remote desktop, tried to move the mouse but it was "stuck" and selecting text on the remote terminal. I typed Ctrl+Alt to release and... bang!

You also asked for the amount of connections. It was the first (and only) connection I opened.

I just got what appears to be the same bug by closing my only connection via the tab bar. Looking to provide a better backtrace, but why are there no debug packages available for libgtk-vnc or vinagre?

Emilio: I tried to download the DEB of 0.4, but that link didn't work.

I also could not find debug packages for libgtk-vnc or vinagre. Also, I tried the 0.4 deb provided above (I downloaded it, but didn't test it until now) and the program still crashes. In my case, all I have to do is connect to a server on the same computer (see duplicate bug).

i can confirm this bug, because I'm having the same problem

0.4-1 is now in the archive, should be built soonish. Let's wait for it.

The package is already available, please test with it.

Thanks.

I'm not 100% sure it's the same segfault, but I am still unable to
connect to the passworded VNC box.

- I start vinagre 0.4
- I click on the "connect" button
- I type the name of a remote machine
- I click on the "connect" button

On the first time I saw it consume "nice" CPU time. On the second time it crashed right away.

In both cases, apport showed me the same traceback on setcontext()/makecontext().

I can reproduce it when I type an IP of my network. None of them have a VNC server listening. If I type a class C IP that can't be resolved in my network, it doesn't crash.

Still crashes with 0.4-1 when trying to connect to a local machine.

...with the same stacktrace. Also, there still isn't any -dbgsym pakages for vinagre.

I'd ask you guys to test vinagre 0.4 against development version of gtk-vnc. If you can't do that, please wait until next week, when gtk-vnc 0.3.3 will be released.

This sounds like dupe of bug #183169

i just had this bug, too.
goodbye,
ilh700.

just had the same crash

Same here with vinagre 0.4-1 in Hardy. All I have to do is try to connect to a non-listening port on localhost. With vanilla vncviewer, the error is:

Mon Jan 28 23:24:59 2008
 main: unable to connect to host: Connection refused (111)

Jonh, for what it's worth, I think these might be two separate issues. There
are a few other issues tracked here other than the "missing hostname" one; I
myself found this bug because vinagre crashed when trying to close the tab
bar.

I upgraded to the latest gtk-vnc and can no longer reproduce my issue or any
of the others here, so perhaps that fixes it as well. Can anyone reproduce
the issues tracked here other than the "missing hostname" one?

I'm not able to make it segfault anymore, but I still can't connect to a
 passworded VNC server (a hardware box) I'm putting on localhost via an
ssh tunnel.

Chris, what's happening? Tell me more details please.
