[Libreoffice] LO with clean configuration unusable

[Lubos Lunak]

 Hello,

 current master, with ~/.libreoffice removed, fails on the first startup, 
showing a dialog about not being able to lauch the application. Subsequent 
launches are successful, but LO is unable to load or save any document (I 
assume the first run resulted in a corrupted internal database about 
plugins).

 The commit responsible for this problem is 
f9496177a4c942f2acc39a978a3cd65689f14d8d in libs-gui. I don't understand the 
code, but apparently the new constraints introduced by the commit are not met 
by code using the class.
