Binary package hint: yakuake

Hi,
I changed the width of yakuake and after a few seconds I pressed the menu button and yakuake freezed...after a few seconds, it crashed. Hope it helps

Can confirm this bugreport. After setting width to 100% and height to 40%, yakuake freezed and finally crashed.

[Tomasz Czapiewski (xeros)]

I can confirm that yakuake segfaults (not freezing) after setting width or height different to defaults.
Clean kubuntu jaunty-desktop-amd64 install from 2009-03-30 snapshot, installed ~30-60 minutes ago, upgraded just after install (now), default settings (+ "yakuake" and "kde" packages installed), no extra repositories.
No additional info to that it just segfaulted (tried "yakuake --nofork" run in konsole), no apport dialog window.
Tested few times - everytime the same result.
Locale: PL.
Package: yakuake-2.9.4-0ubuntu1 (amd64)

And now yakuake has crashed when it was hidden and not in use - apport dialog has appeared and apport properly found this bug by bug report subject.

NOTE: I'm unable to find the duplicate that bugs.launchpad.net is referring to.

BUG REPORT: I confirm the SIGSEGV yakuake (versions 2.9.4) is consistently reproducible by trying to change the height and/or width via the menu in the status bar of yakuake. This happens on 2 out of 3 machines I'm running Jaunty on and use very frequently. I tried to provide a stacktrace/backtrace but need some assistance with gdb or whatever this should be done with. Further, the built in crash handler states the backtrace appears to contain no useful information possibly because (no debugging symbols found). Sorry, I'm not experienced/good with debugging at this point. Possibly relevant: when I run yakuake from a terminal, on the 2 machines with the problem, there is a non fatal error "(<unknown>:10917): Gtk-WARNING **: Unable to locate theme engine in module_path: "ubuntulooks"," and on the one machine I don't have the problem on, I do not get this error.

WORKAROUND: If you use the same menu to open the configure yakuake window first and then change the width and/or height in this new window, there is no signal 11 and yakuake continues to run normally.
