Bug#924448: gimp: Measure tool -> click on image -> Segmentation fault

[Kingsley G. Morse Jr.]

Package: gimp
Version: 2.10.8-2
Severity: normal

Dear Maintainer,

Thank you very much for maintaining gimp!

It's very, very useful!

I seem to have found a way to crash it.

Maybe you can too.

(And ultimately, fix it.)

   * What led up to the situation?

    1.) Run gimp from the command line with
    
        $ gimp
        gimp: LibGimpBase-WARNING: gimp: gimp_wire_read(): error
        gimp: LibGimpBase-WARNING: gimp: gimp_wire_read(): error
        gimp: LibGimpBase-WARNING: gimp: gimp_wire_read(): error
        gimp: LibGimpBase-WARNING: gimp: gimp_wire_read(): error
        gimp: LibGimpBase-WARNING: gimp: gimp_wire_read(): error
        gimp: LibGimpBase-WARNING: gimp: gimp_wire_read(): error
        gimp: LibGimpBase-WARNING: gimp: gimp_wire_read(): error
        gimp: LibGimpBase-WARNING: gimp: gimp_wire_read(): error
        gimp: LibGimpBase-WARNING: gimp: gimp_wire_read(): error
        gimp: LibGimpBase-WARNING: gimp: gimp_wire_read(): error
        gimp: LibGimpBase-WARNING: gimp: gimp_wire_read(): error
        gimp: LibGimpBase-WARNING: gimp: gimp_wire_read(): error



    2.) Create a new image

        File->New->OK


    3.) Select gimp's "measure" tool by 
    
        a.) moving the mouse's pointer over the
            icon of a compass and
            
        b.) clicking the mouse's left button.


    4.) Move the mouse's pointer over the newly
        created image.


    5.) Click the mouse's left button.

    
    6.) Watch gimp crash with

        (script-fu:3615): LibGimpBase-WARNING **: 22:37:47.912: script-fu: gimp_wire_read(): error
        Segmentation fault
    
   * What outcome did you expect instead?

I expected to be able to measure the distance
between 2 points.

I tried to work around the crash with different
options for the measure tool.

No luck.

I hope that helps,
Kingsley
