SOS!

[Leon Pollak]

Hello, gurus.

Recently I was stupid enough to update my FC20 to FC21.
Since that, several things stop working, the worth is gdb under 
kdevelop (4.7.1).

I am doing remote cross-debugging for arm with gdb-7.7 and also tried 
with gdb-7.5.50.

Plane gdbs with the same gdbinit file work perfect.

Under kdevelop, starting the debug session, I receive:
The exception is: MI type error
The MI response is: ^done,threads=[{id="2",target-id="Thread 
880.881",frame={level="0",addr="0x400314bc",func="pthread_yield",args=[],from="/lib/libpthread.so.0"},state="stopped",core="0"},
{id="1",target-id="Thread 
880.880",frame={level="0",addr="0x000bff34",func="main",args=[{name="argc",value="1"},
{name="argv",value="0xbeea2e84"}],file="/Projects/CSU/src/main.cpp",fullname="/Projects/CSU/src/main.cpp",line="47"},state="stopped",core="0"}],current-
thread-id="1"

Pressing OK, gives me my application waiting at the main.cpp BP. 
Stepping over works.
Setting BP at 3 lines later current position already does not - 
application runs without BP.

Running without BP at the beginning works, but there is no way to stop 
the running application - pressing stop does nothing.
Exiting the debugger does not do a thing on the target.

Any help/recommendation will be highly(!!!) appreciated.
Even how to go back to the previous kdevelop version...

Thanks!
