well.. dayjob caught up and got late replying to this thread.

In order to debug this problem further, I removed two feeds(the last two feeds 
seen before akregator hung) and tried importing that opml.

It resulted in a crash.


I have compiled kdepim suite with debug but it seems it always uses libraries 
from /usr/lib and thus the backtrace is not really useful.

How I can make the compiled akregator binary use the compiled libraries, to 
generate a useful backtrace? exporting LD_LIBRARY_PATH didn't help.

Thanks
