SLS v1.3.3 on Ubuntu 22.04 LTS - crash with segmentation fault (core dump)

Once again with the latest version 1.3.3 of Squareline Studio.

Any file choosing dialog crashes the application wtih a core dump.

For instance:
1.) Start SLS
2.) Goto Examples and choose one. Smartwatch.
3.) Push the green Button “Add Files to Assets” on bottom right
=> Segmentation fault (Core Dump)

I use a plain and up-to-date Ubuntu 22.04 LTS (the current LTS version). Nothing special. Also Ubuntu is a very common linux desktop. Do you test your releases? I have tried SLS 1.3.2 und 1.3.1 and no version does work. All have this File chooser bug. This bug seems to be present on MacOS too, as the topic “Crashes on macOS when clicking off the system file chooser dialog” suggest.

All the license stuff does work, but the main purpose of this application does not.

Here is the shell output:

> ~/Downloads/SquareLine_Studio_Linux_v1_3_3$ ./SquareLine_Studio.x86_64 
[UnityMemory] Configuration Parameters - Can be set up in boot.config
Segmentation fault (core dumped)

Hi, we tested your use-case in LMDE (Linux Mint Debian Edition) version 5 and there the native file dialog works fine, a picture was added successfully to the assets, no SEGFAULT whatsoever. Maybe the issue is related to your specific linux distribution Ubuntu.

There seem to be the same issue mentioned here too:

We have a little bit more log information there so will see what could be done to solve this Ubuntu-related issue.
