designer-qt5 V5.11 core dump
-
Using Fedora 29 Linux and noticed recently that designer-qt5 consistently crashes (segmentation fault and core dump) upon closing a "form preview" operation. Doesn't matter what form I preview.
this is the gdb backtrace...
[0_1550132761064_gdb.txt](Uploading 100%)
Anyone else noticing anything similar?
Not using any themes. -
Hi
Superfine with gdb trace but file upload is a bit broken here
so we cant see it.
Could you please paste it or similar? -
Well, apparently the "file upload" function is brain dead so here is the relevant portion of the gdb backtrace
Core was generated by `designer-qt5'.
Program terminated with signal SIGSEGV, Segmentation fault.
