gimp-gap crashes when duplicating frame

[Ryan Kavanagh]

GIMP gives an error when duplicating the frame:
<Start of Error Message>
GIMP Message

Plug-In crashed: "gap_plugins"
(/usr/lib/gimp/2.0/plug-ins/gap_plugins)

The dying Plug-In may have messed up GIMP's internal state. You may want to save your images and restart GIMP to be on the safe side.

<End of Error Message>

I have restarted GIMP three times, two no avail, and tries reinstalling gimp-gap threw adept.

Could you run "GIMP_PLUGIN_DEBUG=gap_plugins gimp" from a command line, when it prints the pid of the plugin do "gdb -p pid", "(gdb) continue", try duplicating the image and get a backtrace if the plugin crashes then?

It did have the issue on first run on my dapper install but now prints a "could not rename frame" message and nothing about the plugin

I've forwarded that issue upstream with a backtrace: http://bugzilla.gnome.org/show_bug.cgi?id=332689

fixed upstream

[Sebastien Bacher (seb128)]

The patch is quite simple if somebody wants to apply it:
http://cvs.gnome.org/viewcvs/gimp-gap/gap/gap_thumbnail.c?r1=1.10&r2=1.11

I am getting this same error and I do not know how to apply the patch or I would.

[Jérémie Corbier (jcorbier)]

Debdiff including upstream fix.
