QtCreator crashing when opening a .ui file (or attempting to access anything related to designer)
-
Hello. Thanks for the response.
There evidently is no separate designer installed with the binary installer of QtCreator which I downloaded from qt-project.org. However, the project I am working on does build Qt from source and this does build a copy of designer which does load.
Note that the same crash occurs if I try to modify any designer related options in the Tools->Options->Designer section in QtCreator.

Qt Creator 3.6 ?
-
Yes sir.
Initially I was using a previous version (3.5.1 if I recall) where the problem first occurred and I upgraded to see if it would fix it. I had a similar problem once before several weeks ago, although I do not know if the error printed to the terminal was the same. A simple reinstall of my current version fixed it at that time. However this time niether reinstalling nor upgrading has helped.

Can you start Qt Creator through gdb to see exactly where it fails ?

Here are partial backtaces from 4 separate instances of the crash. Each one is reproduced in a different way. Note that one of them is a SIGSEGV and the other 3 are SIGABRT. The system is running KDE on OpenSUSE 31.2 with latest patches applied as of the current date.

Did you had any update recently concerning e.g. your graphic card driver ?
-
Recently some updates to OpenSuse were applied. I did reinstall my graphics driver after that. I then upgraded the driver after that. It may be that QtCreator did not work on the older driver either, but I can't recall now. I am about to try a beta of the Nvidia driver to see if that helps. So far Qt Creator is the only program that I am aware of that has no worked recently.
-
I Just tried the lastest beta, and the result is the same. I am fairly sure what motivated me to upgrade in the first place was that qtcreator stopped working properly after reinstalling the version I was using prior to the OpenSuse updates.
-
Really strange. You should take a look at the bug report system to see if it's something known. If not please consider opening a new one providing a minimal compilable example that reproduce this behavior with all the details you can give about your current system (distribution version, driver, graphic card type etc.)

Ok. Will do. thanks.
