Package: gajim
Version: 0.16-1
Severity: important

Hi,

After updating gajim to 0.16.1 it softlocks my laptop right on launch. Laptop
reacts with following:

  1) Display image is not frozen. E.g. mouse pointer can show 'loading'
animation if it was showing it during softlock
  2) Unable to control using laptop keyboard and external USB mouse. However,
touchpad remains functional (at least with regards to moving pointer)
  3) Laptop is not reachable via SSH in softlock state
  4) CPU consumption by one of the cores spikes to 100%. Laptop remains
functional for some time (up to 5-15 seconds) after launch before locking up.
GNOME system monitor with setting 'show all processes' does not show which one
consumes CPU.

The only reliable way i found to leave this state is forced shutdown using
4-second press on power button.

I've seen message about softlock somewhere during boot-up or shutdown (i don't
remember, probably i managed to shut it down once properly).

This started happening after following upgrade:

Few more facts:
  Reverting gajim package to gajim_0.15.1-4.1_all (which i found on debian
repos) restores its launchability
  System functions properly w/o any issues, including running heavy
applications like modern games
  On my work system, where i have similar set-up (mix of testing and unstable)
0.16.1 launched just fine w/o any issues. I also have virtualbox installed in
there, however, i do not have NVIDIA drivers - work PC uses intel card
  When locking up (or when i shut it down), system sometimes writes bunch of
0x00's to kern.log
  Launching gajim from console produces no output. Gajim still softlocks
system.

I admit it might be not Gajim issue (rather kernel-related), however, i have no
idea where to fill this bug as gajim is the only application which triggers it.
Also i need some guidance on which logs to collect/how to debug it, i have
little to no experience with debugging low-level issues.
