Comment 1 Joris Guisson 2009-03-09 19:14:49 UTC 
Does this happen offen ?
Comment 2 Joris Guisson 2009-03-09 19:16:27 UTC 
Does this happen often ?
Comment 3 Robert Sela 2009-03-09 19:46:07 UTC

Comment 6 Joris Guisson 2009-04-07 10:30:39 UTC 
@ jcowin35: that is a bug which is already fixed in 3.2, and has nothing to do with this one.

This is a qca bug, reassigning to qca maintainer
Comment 7 Justin Karneges 2009-04-07 18:13:41 UTC 
Does KTorrent use QCA::Initializer ?
Comment 8 Joris Guisson 2009-04-07 18:20:59 UTC 
Yes, in libbtcore/util/sha1hashgen.cpp
Comment 9 Justin Karneges 2009-04-07 19:26:09 UTC 
I checked the code and I don't see how this is possible.

One suggestion I have is instead of this:
  hash->update(data, len)
do:
  hash->update(MemoryRegion(QByteArray(data, len)))

This will ensure the data isn't implicitly converted to secure memory, which you don't need here anyway.  I'm wondering if maybe there's a bug in the Botan secure memory stuff (I didn't check the code that deep).
Comment 10 Joris Guisson 2009-04-09 09:03:48 UTC 
I can do that, but will this prevent the crash ?
Comment 11 Justin Karneges 2009-04-09 09:20:06 UTC 
I have no idea.  What I'm suggesting is a way to help debug.  I have personally not experienced a crash like this.

I'm thinking this is a ktorrent crash after all, reassigning to me.

Comment 34 Martin Marques 2009-11-05 13:00:38 UTC 
I'm still having the same problem.

All versions of 3.2.x crash.

ktorrent 3.3rc1 just hangs, right after throwing a permission denied on the directory where the torrent is downloading.

Permissions on the directory are OK, so I really don't know where the problem can be.
Comment 35 Joris Guisson 2009-11-05 18:19:15 UTC 
The fix is not in the release candidate, it will be in 3.3.

KTorrent crashed, it was minimised and running when I received this (second in 1 hour) report.
