argv=0x7fffffcfcfa8) at main.cpp:110 The first bt is caused by removing, the second by adding a feed. Can you reproduce this crash or does it just happen occasionally? I had one crash that was removing (unfortunately I closed the window on the bt, hopefully the one above). I have used akregator on another computer (32 bit) with no issue before this, when I moved my feed to this computer and I was moving stuff around after the import it happened then. It happens at random times, and it not reliably reproducable. Please excuse me, I'm having a brainfart (I had it crash 3 times on me while I was moving around and deleting). It only crashed the one time on the feed deletion. I don't know any way to reproduce it reliably, it just happens now and then (more now than then I think). IIRC have I seen this behavior since quite some time, I didn't use akregator for a while becase it was just too unstable. I correct, the second is caused by moving a folder. A way to make it crash on delete: move a folder with subitems, delete a subitem. #0 0x08064d19 in ??
