Building problem

[Bert Wesarg]

Hi,

does anybody has any building problems lately?

I have really a strange problem. After installing Ubuntu 10.04 freshly
on my notebook, I can't run a self build nedit binary anymore. The
error message is;

Error: Shell widget nedit has zero width and/or height

The offender is in source/nedit.c:516:

    XtRealizeWidget(TheAppShell);

I have tried to reproduce this with a minimal X application (see
attached file), which showed the same error, but than suddenly stopped
to show this error.

Any help would be very appreciated.

Thanks.
Bert
