Bug#550183: Breaks Default button in some eclipse dialogs (and rcp apps)

[Andreas Pakulat]

Package: libgtk2.0-0
Version: 2.16.6-1
Severity: important

Hi,

after upgrading libgtk2.0-0 to 2.18.2-1 I'm experiencing problems with
the default buttons of dialogs in Eclipse and Eclipse-based
applications. Trying to click on the button "presses" it down, but
there's apparently no release or click even received by that button. I
tried debugging this and saw that the gtk_button_press_event is being
called, but not gtk_clicked in SWT's Button class. Using Enter to
trigger the button works and seemingly also to click once onto the
button to get it into the broken pressed-state and then pressing the
mouse outside and moving it into the button to release there. This also
triggeres the click.

So far I've seen this in the File->New->File dialog for the Ok button
and for the Cancel button in File->Import (after hitting next). I also
experience this in basically all modal dialogs of an RCP app I'm
developing.

Downgrading to libgtk2.0-0 makes everything work again, but so far I
haven't seen this happening in a pure GTK app (tried gimp, dia and
emacs). Its also not a style problem, I've tried various GTK styles by
now which all show the same problem. Oh and I'm using Eclipse 3.5
directly from eclipse.org not via packages.

Andreas
