[ubuntu-mono] [Bug 1074804] Re: Application Docky Crashes Frequently

[Fred Roller]

I am running Docky on Xubuntu across several machines and several generations 12.04 -14.04 and it is easily reproduced by updating or installing with either GUI (software center or update manager) or CLI apt-get or dpkg -i.  The installation process is what is killing it.  I have attached the following log from an Acer Aspire 7520 AMD 64 (corex2), 4Gb ram, 1 Tb hdd, with Nvidia graphics.  
First killall docky. 
Then docky --debug > docky.log & 
then sudo apt-get install warzone2100 -y 
then wait for crash.  
Do not restart docky 
then killall docky. 
End of steps.

It's an annoyance but not a show stopper.  I have tried on a 14.04 beta2
build with the same results.  The following from the log seems to be the
relevent part:

[snip]
[Debug 12:44:19.621] [DesktopItemService] 2 new application(s) found.

[EOF]

relevent because it is the first mention of the new programs and seems
to be trying update cache.  Could [Info  12:44:20.795] the trigger of
the crash? Just guessing, I don't know enough about programing to say.
Given the age of the post, if the solution has been resolved else where
please point me in that direction.
