Hi,

I finally found a way to debug the kio_svn slave and it seems that something in \
kio_svn::update() is beeing done wrong, causing a segfault deep within libsvn.

This is on a recent debian sid, with kdelibs4c2 compiled with debug=full so the slave \
won't timeout and kdevelop svn from 3.4 branch. I also noted a lot of slave not \
connected to application messages in the kdeinit-output-window but I think this was \
only while the slave was "suspended"..

Now here is the backtrace from the SIGSEGV:

I hope this helps in debugging, later today I'll have kdesdk with debug=full too, so \
that I can provide a backtrace with exact line numbers (I don't know why it's not \
taking the debug symbols from the kdesdk-dbg package).
