Bug 109070

Description:
When launching any LO app and a configuration lock warning needs to be presented, it results in an empty window (just window decoration and window background content rendered inside) and thus it is not possible to proceed any further. Workaround is to manually delete .lock file (rm ~/.config/libreoffice/4/.lock)

It could be a timing issue as at the beginning the bug was observable only when launching with a file provided (i.e. after click in a file manager on a document), but "plain" startup was fine (content of window was rendered), still after playing around with gdb and strace, "plain" startups also started to fail.

Steps to Reproduce:
1. touch ~/.config/libreoffice/4/.lock
2. libreoffice5.3

Actual Results:  
An empty dialog is displayed.

Expected Results:
Configuration .lock file warning is shown.


Reproducible: Always

User Profile Reset: No
