This time I made sure to build with full debug info, and ran it in gdb, with the kde crash handler off (it cant seem to get debug info when ktorrent crashed, dunno why)

The program is running.  Exit anyway? (y or n) y

svn up

I just fixed this.

Ok, seems to work now. I'll follow up with any more crashes I find.

Two issues, on startup I get allot of these:

QApplication::postEvent: Unexpected null receiver
QSocketNotifier: invalid socket 293 and type 'Read', disabling...

and On exit, ktorrent crashes, but not in gdb, which makes me think it might be some uninitilized variables, but I can't be sure. And ktorrent is taking forever to launch in valgrind...

Ok, here we go, valgrind results:

Running KT in valgrind is very slow (most apps are very slow in valgrind)

Those postEvent messages, I still need to look into it.
As for the socket stuff, just ignore it, probably the other side closing the connection.

so far ktorrent is the slowest I've ever seen in valgrind.

How about the invalid reads and writes in the dht code?
ie:

That seems to coincide with the crashes I've seen on exiting ktorrent. (I recall hearing that other people I talk to have the same crash on exit, and one mentioned that stopping torrents before exiting helps, don't know for sure though)

Though since that last svn up I did, it hasn't crashed at runtime, which is good. I do believe it still crashes on exit, but not in gdb, and kde's crash dialog never returns valid info when ktorrent crashes.

This weekend, DHT will be seriously tested, with some luck I should be able to fix most issues with the DHT.
