once in a while the wacomb bamboo tablet works but not very often ?
Tablet support is done by GTK+, and bugs like the failure to detect tablets on startup of a GTK+-based application (especially if the stylus hasn't been used for a while) are still present.
I couldn't reproduce it reliably yet, but changing the tablet input device from stylus to eraser (the other tip of the stylus) could be enough to get it working. And according to some other reports it might be important to run the tablet configuration (from thec control panel, at least for older models)at least once before using the tablet.
There's a number of other tablet-related bugs in GTK+; I didn't check if any of them could apply here.
