Re: [Mscore-developer] Master crashes when opening most dialogue boxes

[Joachim Schmitz]

Have you tried using the native file dialog? You'd need to enable it
manually in MuseScore.ini

I managed to reproduce this crash under Linux Mint 18.1, with Qt 5.8.
It does not crash with Qt 5.6.
Attached the crash log from AddressSanitizer. By looking at the log, it
appears to be this bug:
https://bugreports.qt.io/browse/QTBUG-58762
So, unfortunately, I think it is a bug of Qt, or gtk, or both combined.
Ciao,

[Joachim Schmitz]

Yes, I can. Maybe it is about the native/non-native file dialog?

Do you mean that you (and possibly other as well) can open an existing score
via the "File | Open..." menu command? That it may be a Linux specific issue
or perhaps specific to my system?

Last time I tried (three weeks ago) it was working, with much the same
system and set up as now.

Subject: [Mscore-developer] Master crashes when opening most dialogue boxes

*Context*: self-compiled today master under Linux Mint 17.3, Qt 5.8, Qt
Creator 4.2.1

*Description*: the programme crashes with a segmentation fault when the
"exec()" method is called for many of the dialogue boxes. For instance:

*Steps*:
1) Start MuseScore
2) Select menu item "File | Open..."

*result*: segmentation fault in /mscore/file.cpp/, line 852 (method
/QStringList MuseScore::getOpenScoreNames(const QString& filter, const
QString& title)/).

*Note*: the only dialogue box I was able to open so far is the Preferences
dialogue. This happens when running from within Qt Creator and from a
command line. In any case no error message is provided beyond "Segmentation
fault".

Is this expected as for instance a consequence of some unfinished
development stage?
