Thanks a lot, Tarani. I should read maemo docs more careful :) I found the tip of using valgrind under scratchbox in the Maemo Debugging Guide.<br><br>BTW I watched a top during the application was working. It took up to 80% of memory and about 20% of CPU at some point. So, I'm going to trace it using valgrind.
