Bugzilla Bug 195908

I was having a bug (segfault; I re-emerged all ebuilds listed by something like
emerge -ep world |grep krellm

emerge -va1  app-admin/gkrellm x11-themes/gkrellm-themes
x11-plugins/gkrellm-reminder x11-plugins/gkrellm-radio  x11-plugins/gkrellm-xkb
x11-plugins/gkrellmwireless x11-plugins/gkrellmlaunch x11-plugins/gkrelltop

x11-plugins/gkrellm-hddtemp x11-plugins/gkrellm-leds 
x11-plugins/gkrellm-volume x11-plugins/gkrellmss x11-plugins/gkrellmms

and bug persists:

I have been using this skin for years (at least 2 or 3).

More logs coming.

Hope this is helpfull.

hmmm, maybe it's again that /dev/radio bug I met on debian 4 years ago ...

or gettimeofday() call ? I am having "time problems" with mplayer since my last
update 12h ago: movies are played about 8% too fast; maybe something wrong in
the RTC driver ? Linux API ? ... 

emerge -C x11-plugins/gkrellm-radio
fixed it.

Changing topic from
> app-admin/gkrellm-2.3.0 Segmentation fault

to
> app-admin/gkrellm-2.3.0 Segmentation fault when x11-plugins/gkrellm-radio-2.0.4 installed

Thus removing bug 195522 block.

I tried to reproduce again:
remerge => rebug
remove => solved
and so on ...

Indeed, there is a bug - If /dev/radio doesn't exist, this plugin blows up.

I may devise a simple "Don't segfault, just die slightly more sane" patch.

In the mean time I have removed it from the meta "gkrellm-plugins" package,
just in case.  Hopefully you would only install this if you have a radio tuner
card anyway, and would therefore have this device node present...

Still happens with app-admin/gkrellm-2.3.1

> Still happens with app-admin/gkrellm-2.3.1

Yes, it's definitely due to a bug in the x11-plugins/gkrellm-radio plugin which
has very little to do with gkrellm itself.  I'm sure every version of gkrellm
will segfault in the same way if you try to initialize the gkrellm-radio plugin
without a /dev/radio device present.  I just haven't had a chance to patch the
plugin itself.

If you do, please post the patch here and I'll incorporate it into the
gkrellm-radio plugin.
