[Gutsy] Inkscape hangs when exporting drawing to bitmap (PNG)

I am unable to duplicate on 7.10 with Inkscape 0.45. Are you running 32-bit or 64-bit? Can you give detailed info on how to reproduce the issue?

I have this problem on AMD single core, AMD dual core, Intel single core, Intel dual core. I believe it's mostly 32-bit Ubuntu installed on these boxes.

From a Mac Mini Dual Core with Ubuntu 7.10 32-bit:

aw@macken:~$ dpkg -l inkscape

This is the message after an export of a page with a single object (it hangs until I do xkill):

This is the message after an export of a blank page (this one does a core dump without a xkill):

do you have any use for the core-file? (I dont know where Inkscape puts the file)

On an AMD single core Ubuntu 7.10

I am still unable to see the bug myself, but I think you've given enough information that we can definitely say a problem exists. I'm on KDE, for whatever that's worth.

I get a hang here too. Tho, if left long enough you see that its
simply rendering your SVG into a bitmap. You can reproduce it simply
by making a 2000x2000 page, add alot of detail to it, then try to
render it at 2000x2000 pixels. I think its more an issue of simply not
updating the status bar when exporting.

0.45 could take extremely long to render larger pngs. SVN has had some major fixes wrt this.

I have a crash with this blank/empty page. Its the standard size.

Makeing the report bug #174872 to the upstream project make this bug-report invisible in Ubuntu bugreports. Is this the correct procedure?

If this is an Ubuntu issue this will never be found. In the upstream project this bug is marked as "invalid", but still I have this problem at least five Ubuntu-boxes i have investigated this on until now. Upstream they want me to use a version of Inkscape that is not even released for Hardy, and if this is the solution then the Ubuntu package maintainer would upgrade too.

It would make more sence if it was duplicated an Ubuntu bug.

I have the same problem on (32-bit Gutsy on a single core AMD) but I don't have more skills than posting my gdb-log for the crash. Hopefully it could be useful:
