Hovering results in crash on Linux

sikenbey opened this issue · 4 comments

I use a non-systemd distribution and ILSpy crashes when you hover over a name/button (class/method/variable name on Decompiler tab or Open file button).
Stack trace attached below.

Sorry, we crashed
System.NullReferenceException: Object reference not set to an instance of an object.

I am working on a packaging of ILSpy for NixOS and on 21.11 (stable) - which very much is a systemd-based distribution - I am running into the same issue. Any tooltip/hint rendering results in the above unhandled exception.

Using the release binary for 7.1-rc as building from source gets... interesting :)

Confirmed. Issue no longer reproduces for me on the just-released v7.2-rc. Thank you for the quick turnaround time.
