Description Marvin 2014-11-09 01:05:40 CET
I get too frequent seg faults when using newsgroups. I use gmane and SSL.

Some examples:

1) error 14 in wqy-zenhei.ttc

2) error 14

3) error 4 in libgnutls.so

I think these coincide with network pressure, i.e. network bandwidth is limited due to bandwidth consumption. So whenever the network is busy and slow these happen.

Some details:

linux 3.16.3
claws-mail -V    
Claws Mail version 3.11.0
runtime GTK+ 2.24.20 / GLib 2.36.4
buildtime GTK+ 2.24.20 / GLib 2.36.4
Compiled-in features:
 libetpan 1.5

I'm trying 3.11.1 now.

Followed the intsructions but could not get a crash. I suspect that gdb serializes away the code path that leads to a crash. I could not get a crash just running without gdb either though. So -g might also effect the outcome. Perhaps that's a clue but not much of one I know. I'll try gdb -p <pid> and see if that is different. If you have any other ideas I will try them if I'm able.

This is in 3.11.1 it is definitely an issue when the network is saturated by utilizing downstream bandwidth.

This was not with -g unfortunately.

These seem to be the significant entries from stdout

gtkcmctree.c:3668 Condition node != NULL failed

0:  /bin/claws-mail(gtk_cmctree_expand+0x158)

24: /bin/claws-mail(grouplist_dialog+0x965)

Also from the kernel:
traps: claws-mail[19393] general protection ip:7f2982695830 sp:7f297ea319c8 error:0 in libetpan.so.17.1.0

Do to freq. of crashes while using nntp I'm guessing the feature is not used by many others.
