GPaint is not a supported application for Ubuntu Netbook Remix. This does not mean we won't fix this necessarily, but this will be low priority.

[Torsten Spindler (tspindler)]

Unsupported application.

[Caroline Ford (secretlondon)]

I'd no idea there were specific supported applications for netbook remix!

It's certainly a member of universe though and edubuntu.

[Torsten Spindler (tspindler)]

You are right, of course gpaint is supported through universe and edubuntu. Please ignore my last comment.

Which version of gpaint is this? I can't reproduce on hardy.

[Caroline Ford (secretlondon)]

The debian bug says this is in intrepid. Intrepid has the same version of gpaint as hardy.

This is either an issue with a library change, or maybe certain locales.

Did the original submitter also submit to debian? It would be better to see if anyone could reproduce first, debian don't really want all Ubuntu bugs.

From the debian bug:

Package: gpaint
Version: 0.3.3-1
Severity: normal
User: <email address hidden>
Usertags: origin-ubuntu intrepid

*** Please type your report below this line ***

Open gpaint and click the fonts selector and press OK will get segfault.

The tool->canvas is only set on tool_palette.c on_tool_select() at line 400:
    canvas_set_tool(canvas_lookup(GTK_WIDGET(tb->widget)), tb->tool);
Which means the users have to click the text-tool button at least once
to set the tool->canvas to avoid the crash.
