Comment 14 Florian Bruhin 2016-04-26 09:08:08 UTC
I've also seen this crash (100% reproducible) since updating to Qt 5.6 with my PyQt application.

I've now reported it upstream: https://bugreports.qt.io/browse/QTBUG-52988

Comment 15 Raphael Groner 2016-04-26 09:36:12 UTC
Propably:

https://codereview.qt-project.org/#/c/147261/

Is that patch included in our package?

Comment 16 Florian Bruhin 2016-04-26 09:42:44 UTC
That change was abandoned and replaced by [1] which made it into Qt 5.6.0. It's also a fix for a Windows-only bug[2] so I'm not sure if it's related.

Comment 18 Rex Dieter 2016-04-26 11:01:37 UTC
No, the change reference in [1] was abandoned as the wrong approach

Comment 19 Rex Dieter 2016-04-26 11:03:13 UTC
(Sorry, I referenced comment #15), comment #16 got it right

Comment 20 Raphael Groner 2016-08-04 16:21:49 UTC
Rawhide, see bug #1363936 and bug #1330419. Line numbers of backtrace differ with a small offset, propably cause of Qt 5.7 (f25) vs. Qt 5.6 (f24).

Comment 21 Raphael Groner 2016-08-04 16:22:16 UTC

Comment 22 Jerry James 2016-11-28 05:05:23 UTC
Some bugs filed against the mscore package have backtraces that look the same: bug 1336203, bug 1351523, bug 1352381, and bug 1364759.  I'm getting that same mscore crash on F-25, which has Qt 5.7.

Comment 23 Fedora End Of Life 2017-02-28 09:57:26 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 26 development cycle.
Changing version to '26'.

Comment 24 Aaron Sowry 2017-03-01 21:53:36 UTC
I'm seeing this on Fedora 25 too, perhaps the version should be updated.

Comment 25 Than Ngo 2017-07-18 12:01:34 UTC
it's fixed in 5.7.1-19, i will push the it into f26 update today.
