QDevelop won't startup anymore

1) Please try to run latest version of QDevelop (http://code.google.com/p/qdevelop/downloads/list)
2) Run QDevelop and gdb and get backtrace:
$ gdb qdevelop
> run
...
qdevelop: pthread_mutex_lock.c:87: __pthread_mutex_lock: Assertion `mutex->__data.__owner == 0' failed
> back
...
...

After "back" command you will see backtrace. Please provide it.

Please try to remove uim-qt from terminal:

sudo apt-get remove uim-qt

Hope this helps

Marcobra:
I Tried your sudo trick: sudo apt-get remove uim-qt - it resulted in the following
  Reading package lists...
  Building dependency tree...
  Reading state information...
  Package uim-qt is not installed, so not removed
  0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
Pity, That didn't do the trick

Divius:
I only found unstable releases - qdevelop-0.27 svn381? is that what you meant?

Thnx for looking into this problem, but no solution yet

What changes have you done recently?
Please provide versions of all Qt's components and your OS.
And please try latest unstable release of QDevelop.

Maybe the error occured after I tried to install Phonon. Not sure though.
Ubuntu 8.04 - QT 4.3.3
Latest unstable release of QDevelop stopped with:
   henk-desktop ~: qdevelop
   qdevelop: error while loading shared libraries: libQtSql.so.4: cannot open shared object file: No such file or directory

Where can I find libQtSql?

Please do following things:
a) Provide result of

b) Try to build qdevelop yourself from latest source code (see http://code.google.com/p/qdevelop/downloads/list) and test it. Provide result of ldd for new binary as well.
