Bug#36881: Program unuseable/unrecoverable after changing the user-interface

[uplawski at quercus.franken.de]

Package: kdevelop
Version: 2.0.2 (using KDE 2.2.2 )
Severity: normal
Installed from:    Unspecified Linux
Compiler:          gcc-2.95.3
OS:                Linux
OS/Compiler notes: SuSE-RPM or Compiled from source , same effect

Hi.
I wanted to test a different window-layout 
with KDevelop 2.0.2. This was the first time,
I tried the midi-window layout.

As it was not very useful to me, I tried to
set it back to tabbed view. This did not work
as expected. I am still left with two separate
windows (not midi but toplevel-windows, 
though).

1. Those windows cannot be combined into one,
neither by repeatedly using the configuration
dialog, nor by drag&drop.

2. Loading source-code files takes too much
time, now and sometimes KDevelop crashes.

3. Loading another project crashes the 
application. I just do it... load one project.
Load another one. Okay, here is my first
crash-report for today:
-------------------
0x4136b5a9 in __wait4 () from /lib/libc.so.6
#0  0x4136b5a9 in __wait4 () from /lib/libc.so.6
#1  0x413d3ad8 in __DTOR_END__ () from /lib/libc.so.6
#2  0x411d5495 in KCrash::defaultCrashHandler ()
   from /opt/kde2/lib/libkdecore.so.3
#3  <signal handler called>
--------------------

4. Upon quitting, the Application crashes.
To deliver the (will-be) attached crash-report
I go _now_ to the application, and simply
quit it... just so.
Et voilà, crash-report #2:
---------------------
0x4136b5a9 in __wait4 () from /lib/libc.so.6
#0  0x4136b5a9 in __wait4 () from /lib/libc.so.6
#1  0x413d3ad8 in __DTOR_END__ () from /lib/libc.so.6
#2  0x411d5495 in KCrash::defaultCrashHandler ()
   from /opt/kde2/lib/libkdecore.so.3
#3  <signal handler called>
---------------------

Do I have to say, that these are 
reproduceable? And they are, after I have
_uninstalled_ kdevelop and reinstalled it
again!! Irrespective of the 
installation-method.

And now I have no working IDE. 

PSE gimme a tipp, I am lost.
