[sane-devel] Xsane crashes the second time I run it

[Alessio Medici]

Hallo!
	I have got an hp 4200 scanner and I use sane 1.0.6 (with the 
hp4200 pathches for the 1.0.5 version) with xsane 0.81. Scanimage works 
perfectly, but I have a problem with xsane. When I run it the first time  
it works. The second time it exits with a "Segmentation fault 
message". The only way to avoid this error is to remove the file 
Hewlett-Packard:HP-4200.drc in ~/.sane/xsane.

I have enabled the debug messages (setting both SANE_DEBUG_DLL and 
SANE_DEBUG_HP4200 to 127) and this(*) is what I obtain.

Has someone got any idea?

Thank you very much

Alessio Medici
