Update for Upower 0.99

This patch adds a conditional check for a change upower 0.99 requires, obviously things will still work with upower 0.9.23 and before.
Comment 1 Jani Välimaa 2014-07-08 19:43:05 CEST
After applying this patch to xfce4-settings 4.11.2 (+ UPower 0.99.0) in Mageia Cauldron (latest development version), I see segfault at startup. Other users have also reported similar issues.

xfsettingsd[3380]: segfault at 0 ip b6de6bcd sp bffbd2d4 error 4 in libupower-glib.so.2.0.0[b6dd9000+25000]

I'm also seeing messages like this in .xsession-errors:

(xfsettingsd:3380): libupower-glib-WARNING **: Couldn't connect to proxy: Timeout was reached

  If it's crashing, can you get a backtrace with debug symbols? Maybe we can track it down that way.

  For the warnings you can try launching xfsettingsd with --g-fatal-warnings and it will crash on a warning, a backtrace of that would help us eliminate those runtime warnings too.

GDB backtrace

Here's the bactrace after attaching gdb to running xfsettingsd process after startup.

Applied patch from bug 11045 comment 1 to see if all this is somehow magically related to forking issue and seems it fixed the segfault.

I'll apply the patch also to Mageia xfce4-settings package and ask feedback from other users.
Comment 5 Samuli Suominen 2014-07-28 10:31:40 CEST
For what's it worth (not much :), I'll just say it:

This patch is in use at Gentoo's Portage ~arch (~arch equals to something like "testing" or "unstable")
And most Gentoo users use ~ərch, so most Gentoo Xfce users are using this patch, and we haven't received any bug reports about it
So far, all good
Comment 6 Eric Koegel editbugs 2014-07-28 11:00:21 CEST
Oh awesome! I was just waiting on my Mageia box to finish building to I could update it to Cauldron. I guess I'll hold off in hopes I accidentally fixed it :)
Comment 7 Jani Välimaa 2014-07-28 13:22:29 CEST
Affected users confirmed in downstream bug report [1] that after applying the patch from bug 11045 xfsettingsd doesn't segfault anymore with UPower 0.99 patch.
