MDI UI modes - switching problem & a crash

Hi Falk,

obviously this is not consistent. The IDEAl tabs were gone the first time I 
tried again an hour ago. Afterwards, however, I could not reproduce this 
behaviour again.

--- BUT ---

KDevelop crashes here when I try to switch the other way around - from mdi 
IDEAl to any of the other mdi modes.
I then upgraded to latest CVS at about 23 hours but the crash remains. The UI 
modes seem to have switched, however, as the IDE does start in the newly 
selected UI mode afterwards.
Please find a backtrace attached.

I am not on KDE3.2HEAD unfortunately (not enough free disk space to compile 
debug versions here :-( ), so I have to live with standard SuSE 8.2, KDE 
3.1.4, Qt 3.2. Hope the backtrace helps all the way nevertheless.

Bernd
