Bug 162610

Version:           1.9.51 (using 4.00.80 (KDE 4.0.80 >= (KDE 4.1 Beta1), compiled sources)
Compiler:          gcc
OS:                Linux (i686) release 2.6.24-gentoo-r8

Today, after I did the following steps in Kmail (with an IMAP account), it crashed with the backtrace below. Regrettably I was not able to reproduce this crash so far. I use kdepimlibs r812282 and kdepim r812462

1) Switch standard layout to "horizontal 3 pane layout" [Configure KMail -> Appearance -> Layout -> Show message preview pane next to message list]
2) Move the borders of the message preview pane
3) Switch from long folder list to short folder list [Configure KMail -> Appearance -> Layout -> Short folder list]
4) read some mail
5) Switch back to standard layout but still keep short folder list
6) move borders of message preview pane
7) Switch back to long folder list

Application: Kontact (kontact), signal SIGSEGV
