The only recent change in PeerViewItem is the addition of the GeoIP stuff.
Probably a small bug in that code.

I cannot reproduce that crash. Is there a way to make it happen or it just happens sometime?

just happens...

if it is supposed to be in the peers view, perhaps is triggered by peer with strange ip (no geoip flag or something?).

perhaps I could run in under gdb but don't have idea what to look for?

I don't think it's triggered by GeoIP. We use it only when constructing object and it's deleted right after. Flag is also set at that point and we don't touch anything of that at all from that point on.

Crash happened when destroying PeerViewItem object and that would be when we got rid of the peer. We don't do anything when destroying this object and the crash is in ~QListViewItem (). Something surely triggered it but I'm not sure what could that be.

This crash happened only once?

few times... anyway I'll try to find it out

i do not want to open a new thread for that

i got ktorrent that crashes after i go in the pref and deselect enable DHT and click apply. it crashes as i click apply

svn 527444

argh it happens once and i can't get it happen again ...

Why are you posting in a topic that has obvious another bug involved?
This makes things difficult to read.

sorry

just happens...

Did you do a make install when you updated ? If there are old plugins lying around this can cause weird crashes.

Maybe offtopic, but I can't reproduce it either.

plugins are fine, I cannot reproduce it either, hope never happens again

there is definitely something wrong with the peers view (info widget) got KT crashed again with the latest snapshot as of yesterday, Apr 10th.

here is different backtrace I don't know if it is same "bug"-related but perhaps could be useful:

still trying to find more details...

This happens at exit, haven't seen any crashes like that.

I disabled infowidget. It haven't crashed yet since then.
