Please mark this bug "confirmed". I have the same issue, with the most recent Fedora 16 rpm version of ktorrent (ktorrent-4.2.0-1 with ktorrent-libs-4.2.0-1, kde-plasma-ktorrent-4.2.0-1 and libktorrent-1.2.0-2). My drkonqi output is the same. My ktorrent instance was installed with yum, not compiled by me from source.
ktorrent starts normally after moving ~/.kde/share/apps/ktorrent to a different directory. It may be that a malformed torrent or some such is required to trigger this bug.
Here is my drkonqi output with debug symbols loaded: Application: KTorrent (ktorrent), signal: Aborted Using host libthread_db library "/lib64/libthread_db.so.1". 82 T_PSEUDO (SYSCALL_SYMBOL,

That is not the same bug, that is bug 294996
The only way I can see this happening is when you load plugins from a previous version of ktorrent, make sure everything from the previous version is uninstalled before you install your own self compiled version.
Completely not reproducible, closing, reopen if you can reproduce it with 4.3
