[Lazarus] Regular Lazarus crash when starting a new project

[Michael Van Canneyt]

Hi,

I'm getting a regular lazarus crash when starting a new project that opens a
dialog that allows you to configure the project (fpcunit, web browser..)

Today's lazarus from git. Linux 64-bit, gtk2 widgetset, linux mint running cinnamon.

Console output:
-----
Hint: (lazarus) [TBuildManager.SetBuildTarget] Old=x86_64-linux--gtk2 New=x86_64-linux--gtk2 Changed: OS/CPU=True LCL=False
----------------
Hint: (lazarus) [TMainIDE.DoOpenProjectFile] "/home/michael/projects/fresnel/demo/Basic/basic.lpi"
Hint: (lazarus) [TBuildManager.SetBuildTarget] Old=x86_64-linux--gtk2 New=wasm32-wasi-browser-gtk2 Changed: OS/CPU=True LCL=False
The program 'lazarus' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
   (Details: serial 111751 error_code 3 request_code 12 minor_code 0)
   (Note to programmers: normally, X errors are reported asynchronously;
    that is, you will receive the error a while after causing it.
    To debug your program, run it with the --sync command line
    option to change this behavior. You can then get a meaningful
    backtrace from your debugger if you break on the gdk_x_error() function.)
----

Projects that do not open a project configuration dialog seem unaffected.

I recently switched to using a docked IDE, maybe this has some influence ?

Any hints, things I can try ?

Michael.
