Hard times debugging under KDevelop

Hi,

 A little bit offtopic, but I have problem with debugging under KDevelop and 
the problem happened only recently and in some way it is related to 
KDirWatch, thus I'm posting it here. The symptoms: debugging often stops when 
next/step/print is issued in gdb (well, from KDevelop, but basicly this is 
what KDevelop sends to gdb). I can interrupt the execution and I always see 
that the program is "locked" in libpthread.so.0. Here is an example:


(gdb) next <---- here I don't get back the gdb command prompt 

Program received signal SIGINT, Interrupt.
0x41a00a78 in write () from /lib/libpthread.so.0
(gdb) info thread 
* 1 Thread 16384 (LWP 11288)  0x41a00a78 in write () from /lib/libpthread.so.0
(gdb) backtrace 
#0  0x41a00a78 in write () from /lib/libpthread.so.0

#2  0x4094a7b4 in KDirWatchPrivate::dnotify_sigio_handler(int, siginfo*,

(gdb) info local

(gdb) frame 0 
#0  0x41a00a78 in write () from /lib/libpthread.so.0

I've tried to play with "set scheduler-locking", but without success. By 
default it is set to "off".

Any idea how can I debug my programs? It's very hard to do now.
I use gdb 6.0 now (the same happened with 5.3), kernel 2.4.20 (suse), g++ 
3.3.1 (suse) and glibc 2.3.2.
