Experimental patch
As showQuickButtons() is already called inside updateQuickButtons() (and with
buttonsGrid properly created), this fix the problem.
I just can't explain yet why the crash happens only if the konversation window
is hidden.
Patch is applied to svn trunk, will be in 0.20. Thanks for the report and patch. |
Version: 0.19+ (revision 521725 from svn) (using KDE KDE 3.5.1) Installed from: Mandriva RPMs Compiler: gcc 4.0.2 (4.0.2-1mdk from Mandriva) OS: Linux Steps to reproduce: - Open konversation - Having many different servers and channels on the server list dialog may make reproducing easier (I have 3 servers, one server with around 6 auto-join channels and the others 2 servers with 2 channels each) - Select all servers and click on "connect" - Quickly closes the konversation window (it will go to the systray), before the connection finishes and any channel tab wasn't created yet - Konversation crash with this backtrace: Using host libthread_db library "/lib/tls/libthread_db.so.1". `shared object read from target memory' has disappeared; keeping its symbols.

Looks like calling showQuickButtons() before updateQuickButtons() in the constructor is the cause of the problem. But I can't explain why this causes the crash only when the konversation window is hidden.
