By default, Bugzilla does not search the list of RESOLVED bugs.
You can force it to do so by putting the upper-case word ALL in front of your search query, e.g.: ALL tdelibs
We recommend searching for bugs this way, as you may discover that your bug has already been resolved and fixed in a later release.

tdm_greet crash when SAK is enabled

Hello, running current R14 in CentOS 6, I have the following crash only when "UseSAK=true" is set in "tdmrc".

in /var/log/tdm.log (extract):

GThread-ERROR **: GThread system may only be initialized once.
aborting...
[kcrash] TDECrash: crashing... crashRecursionCounter = 2
[kcrash] TDECrash: Application Name = tdmgreet path = <unknown> pid = 9483
[kcrash] Warning: socket connection failed: : No such file or directory
[kcrash] TDECrash cannot reach tdeinit, launching directly.

Kcrash file is attached.

No problem when "UseSAK=false".

tqt3 : fix glib initialization causing error in Glib < 2.24

According to this documentation:

https://developer.gnome.org/glib/2.34/glib-Deprecated-Thread-APIs.html#g-thread-init

"Since version 2.24, calling g_thread_init() multiple times is allowed, but nothing happens except for the first call."

=> CentOS 6 is using Glib 2.22

Hopefully there is a "g_thread_get_initialized ()" function.

As both of those functions are deprecated, perhaps the modified block of code should be wrapped in compile-time glib version checks?

Patch looks good; pushed to GIT in hashes 32bd035 (qt3) and 5b1e219 (tqt3).

Thanks for reporting, and for the patch!
