I can't reproduce with a stable Qt version. Please install the debug package for kontact and try to get a better backtrace.


>#11 0x0000003c37a24bff in ?? () from /usr/lib64/libkontactprivate.so.4

You'll right, I'm testing with Qt 4.7.0. I'll post a better backtrace ASAP.

Backtrace with requested debug info packages installed.

I can reproduce this with KDEPIM 4.5 / KMail 2. It isn't really an issue to have a crash with Qt 4.7 and an outdated KDE PIM stack, but I know now consider this bug to be a serious one.

kontact (4.4.5) on KDE Platform 4.5.2 (KDE 4.5.2) using Qt 4.7.0

- What I was doing when the application crashed:

I have changed icon size on the left bar in main kontact window (bar with mail, address book and other stuff) from small to big. Icons correctly changed their size. However when I move mouse pointer over icons kontact crashes. Moving mouse pointer only on scrollbar near icons and scrolling on it works just fine and correctly.

Change appearance of leftside buttons to «big».

Qt 4.7.1 doesn't solve this, but comes close. Can anyone review this for KMail 4.4.8? Is this bug present in Kontact 4.5.7x?

[Comment from a bug triager]
Bug 250138 seems related to this. It seems to be related to Qt 4.7.x; as there are several comments confirming this doesn't happen with Qt 4.6.x

Can you merge this with bug 250138 ? It's essentially the same thing, but bug 250138 seems to have more activity.
