Description Shayne Johnson 2009-04-05 08:09:45 UTC

Version:           2.9.4 (using KDE 4.2.2)
OS:                Linux
Installed from:    Ubuntu Packages

The dropdown menu with the wrench contains options to change the width and height of the Yakuake window. Using this menu to alter the size of the window causes Yakuake to crash. Going into the settings dialog and resizing that way does not cause a crash.

Comment 1 Eike Hein 2009-04-07 01:06:07 UTC

Preliminary investigation suggests that this crash only happens with Qt 4.5 (which explains why it wasn't reported earlier).

Comment 2 Eike Hein 2009-04-11 14:26:37 UTC

Comment 3 Eike Hein 2009-04-11 14:27:45 UTC

In addition to only happening with Qt 4.5, this crash also seems to disappear here when Qt is built in debug mode. Hence I've been unable to get a useful backtrace so far.

Comment 4 Eike Hein 2009-04-11 19:37:36 UTC

I've now finally been able to produce a useful backtrace, and the crash does indeed happen inside Qt. I'll investigate further and we'll see whether this ends up being a bug report to Nokia or whether a workaround inside Yakuake is in order.

Comment 5 Milos Jakubicek 2009-04-15 23:27:18 UTC

I can confirm that this indeed happens only with Qt 4.5

Comment 6 Rex Dieter 2009-04-16 01:26:52 UTC

Reproduced here, 

rpm -q yakuake
yakuake-2.9.4-2.fc11.i586

on fedora11(beta) with backtrace goodness:

Comment 7 Eike Hein 2009-04-16 14:24:10 UTC

Sorry, turns out I attached the fix message to the wrong bug (bug 189332, the duplicate). This bug is fixed in SVN since r952380 / April 11th, and a 2.9.5 release containing this and other fixes is planned for the first week of May (string freeze went into effect yesterday).
