Nautilus crash when IM preedit

I can confirm it.

I encounter the same bug , using ubuntu 10.10 .........

I'm not as certain it's really a bug in ibus. The same search and typing in chinese characters (gibberish though, not going to give out any results) in List View yields no crash. On the other hand, I can reproduce this as soon as I set IBus as an input method and set it to something other than Off in Icon View or Compact View.

backtrace of below handling with dbgsym packages.

 1) run gdb
 2) open nautilus
 3) gdb> attach nautilus's pid
 4) type "m" with ibus to nautilus's window.

I found that Nautilus crashes also when using scim-bridge, so the bug might be in Nautilus.

Sorry, I forgot to write the difference from the case using ibus.

When using scim-bridge, Nautilus crashes by starting preedit.

Yet another Backtrace is here. (from dupes LP#630886, thanks Jesse)

Umm ... even if using neither IBus nor SCIM, Nautilus crashes just type Ctrl+Shift+u.

Oops, sorry, I posted a halfway comment by mistake.

Even if using neither IBus nor SCIM, Nautilus crashes by just typing Ctrl+Shift+u, which is a trigger of unicode input.

IRIE seems to be right. I am able to reproduce a backtrace following IRIE's description, as attached

Hmm... I make diff of lucid/maverick. That includes some interested changes....

I test with attached patch, I could not reproduce problem. And, i put to my ppa for test purpose.

Could you please test it?

This patch is simple, nautilus_icon_container_search_preedit_changed() rollbacks to lucid.
IMHO, maverick's that routine does not has im-context, but im-context is essential for pre-edit phase.

I can confirm the patch appears to fix the issue, so I marked this bug Invalid for ibus and Triaged for nautilus. I applied the patch to a local copy of the maverick nautilus branch, which I just pushed to LP and should appear on this bug report shortly...

Just pushed in the queue :)

This bug was fixed in the package nautilus - 1:2.31.92-0ubuntu2
