[dev] [bug] wmii segfaults on sudo wireshark

[dtk]

Hey guys,

my wmii with rumai segfaults when I run wireshark as root.

Running wireshark as my default non-priviledged user works fine, as does
running wireshark as root under awesome/gnome.

The wireshark splash displays nicely, showing the modules being loaded,
and I can glance the error dialog stating that some lua functionality
has been disabled, due to being run as root, before wmii crashes, gdm
reloads and prompts me with the user selection to log me in again.

Can anybody confirm this behaviour?

No. Maybe try sudo -E.
Putting wmii into a loop:
while :; do
  wmii
done
helps not loosing state somehow. Here it recovers tags etc.

Still using wmii-3.6, wireshark-1.4.2 (maybe without lua support. I
never tested it)

No. Can you perchance provide a backtrace?

Thanks,
