Crash when opening the snippet editor
Happens on 4.1.4997-dev (3e7dbdea). I updated macOS to 14.4.1 (23E224) today, which I hope is not relevant.
Update: it works fine on the stable release (4.0.4958 (ddff9339))
Update: the crash is introduced in 4.1.4972-dev
Weird enough, this only reproduces on a release build from the build server. It does not reproduce locally, despite also being a release build

As can be seen from the stack trace, the crash is somehow related to syntax highlighting. Setting snippets.syntaxHighlight to false avoids the crash, which can be used as a workaround for now
I am unable to determine the root cause of the crash, and I start to suspect that Qt is at least partially responsible for the crash. What I know is -- not surprisingly -- if I comment out this line, the crash is gone: https://github.com/Vector35/snippets/blob/master/QCodeEditor.py#L64. And I tested it is the large amount of calls setFormat that causes the trouble. Even if I change the code to always highlight a same char with a bare QColor, the crash still happens
