Bug 151627

What kind of Wacom tablet do you use? I've got a Grapphire USB one and it works
as expected (just tried it with the ink tool). Do you get any error messages
while doing this when running GIMP from the command line?

Wacom tablet CTE-430 (Graphire 3, USB) with linuxwacom-0.6.4-6.  The only
warnings I get /immediately/ at pen-down is "(script-fu:26886):
LibGimpBase-WARNING **: script-fu: wire_read(): error", which is why I gdb'd it.
 I didn't think script-fu had much to do with it.

I can recompile the gimp from the source rpm and try to turn off stripping, if
that helps any.

A little system/config info:

My video card is an Nvidia GeForce FX 5700, using NVidia's drivers, 1.0-7167.

You needn't rebuild the GIMP, just download and install the corresponding
*-debuginfo packages for gimp and gtk2 from:

http://download.fedora.redhat.com/pub/fedora/linux/core/updates/3/i386/

Ok, I'll run gimp under gdb w/ the debug info when I get home tonight.

Hmm, can't see something obvious right now, but I'm not that familiar with the
GIMP's innards either. Before I raise this issue upstream it would be good if
you could tell me what settings you have for the tablet in GIMP
(Preferences/Input Devices/Configure Extended Input Devices; Dialogs/Device
Status) and a complete list of packages installed ("rpm -qa | sort"), just to
rule out that I haven't got an update you haven't and vice versa.

Created attachment 112275 [details]
package list for my system

The Stylus/Eraser I have set to "window" mode, and the Cursor I have set to
"screen" mode.  All other settings are defaults.  I've tried setting the
Stylus/Eraser to "screen" mode, and that didn't help any :(  I can definitly rm
-Rf ~/.gimp* and start from scratch too.

Does this problem still exist with current versions of the package (gimp-2.2.11
on FC4 or FC5)?

gimp-2.2.11-0.fc4.3

No problems with the above package.  This issue was quite some time ago, and I
think I may have simply upgraded to FC4 from FC3 to fix this, among many other
problems (.. that I can't seem to recall now)

Thanks for reporting back!
