kstars segmentation fault in Fedora 33 was created by Eric Matlis

Hello-

I am experiencing an instant segmentation fault when I try to start kstars on a Fedora 33 system. Both stable and bleeding packages have this issue. I am attaching a backtrace log file. Please let me know if there is anything further I can do to help.

Thank you.

I think the issue was investigated here: bugzilla.redhat.com/show_bug.cgi?id=1881915, I have yet to test the change to the build as I have not installed F33 anywhere yet. I will work on that.

There is a new package being created now for you to try. You can watch its progress here: copr.fedorainfracloud.org/coprs/xsnrg/ks...eding/build/1707405/

When (if) it builds successfully, you can do a `sudo dnf upgrade kstars --refresh` to make sure you get the latest package, assuming you have enabled the Copr.

Wow! That's cool. Thanks for the quick response. I'll install as soon as it's ready and report back. And yes, I'm using that repo.

Unfortunately still crashing in F33. See gdb log file. I did have to add the stellarsolve repo for a new dependency.

Ok. Keep in mind I only installed debuginfo rpms for kstars and indi. Not the QT libraries. So if the problem is in how kstars interacts with QT, I'm guessing my backtrace won't help you .

I am suspecting that it is just something missing in the runtime that needs to be included in the spec file. I am going to try to build a F33 container to play with in a bit. Installing kstars should have forced some Qt5 packages to be installed with it if they were not already installed, so will see what the container does. If you want to pollute your system to get more information about the crash, I think `sudo dnf --enablerepo=fedora-debuginfo install qt5-qtbase-debuginfo` may be enough to fill in some blank spots.

Thanks for that dnf suggestion. Here's the backtrace log with those rpms installed.

Incidentally, I'm using the following to create the logs:
gdb
> run
# program crashes
> set logging file backtrace.log
> set logging on
> thread apply all bt full
> set logging off
> quit

Back to looking at this, I am able to reproduce it with the Docker container, and it does seem to be the error mentioned in the Fedora bug report in my initial response. I thought I had implemented the work-around in the latest build, but it did not work, so there are a couple other options to check. Will report back.
