Bug#842926: [musescore] Segment violation when Musescore opens with wizard (start center) active.

[Fenix]

Package: musescore
Version: 2.0.3+dfsg1-2
Severity: normal


     Dear maintainer:

     When I try to open Musescore I get a segmentation fault. When I try 
to open again, I get a message for get the last session. If I select 
"yes", the program runs correctly. If I select "no", the start center 
tries to open again and I get the segment violation.

     If I uncheck the 'show start center' (I don't know if those are 
exactly the words in english. It is the wizard init window) option in 
the configuration, Musescore works fine.

     It seems that something goes wrong with the 'start center' window.



     Thanks.
