Comment 1 Dario Andres 2009-11-21 15:32:12 UTC
- Does Konqueror crash again if you repeat the situation you described ? Have you tried using Dolphin ?
Thanks
Comment 2 doc.evans 2009-11-25 20:00:58 UTC
1. No, this has just happened once (so far). I suspect some kind of race condition because I think (about 98% sure) that I had clicked to start a second FTP between the same two machines.

2. You don't want to know my opinion of Dolphin :-)
Comment 3 Dario Andres 2009-11-25 20:02:59 UTC
Filemanagement in Konqueror is done using the Dolphin KPart.. I just wanted to know if this could be unrelated to the Konqueror code itself...
Thanks
Comment 4 David Faure 2009-11-27 23:16:15 UTC
The crash is deep inside KIO, can't be related to konqueror or dolphin.
The backtrace only says "memory corruption" to me, though, doesn't really tell me where the problem is. If it happened more often I'd suggest running it in valgrind, but if it works 98% of the time....
Comment 5 FiNeX 2009-11-29 22:30:19 UTC
@David: shouldn't this report moved to KIO?
Comment 6 Dario Andres 2009-12-09 23:23:47 UTC
Moving to KIO
Marking as NEEDSINFO until we get more crashes and/or steps or information on how to reproduce
