xsane coredumps inside snapscan backend with current devel packages
Last modified: 2007-11-30 17:11:13 EST
I upgraded something like 400 packages on my machine today to current devel
packages. After this, xsane coredumps upon startup when trying to access my
Epson Perfection 2480 scanner, which uses the snapscan driver. I installed
sane-backends-debuginfo and got this stack trace:
#0 0xb7687572 in sanei_constrain_value (opt=0x974cde0, value=0x0,
info=0xbf9bacc4) at sanei_constrain_value.c:123

I tried backing out to old versions of sane-backends, gtk2 and glibc, the three
packages that seemed from the stack trace to be relevant, but backing out didn't
make the problem go away, even though I wasn't having the problem before I
upgraded today. I found that I was able to make xsane start properly by
unplugging the scanner's usb cable, unplugging its power cable, plugging the USB
cable back in, waiting 10 seconds, plugging the power cable back in, and then
running xsane again. However, I subsequently exit and restart xsane without
repeating that whole process, I get the coredump again.
As I say, I don't think this was happening before, but I can't prove it since I
wasn't able to find a combination of old packages which made the problem go away.
I have current devel versions of all the packages installed on my system as of
about a half hour ago on ftp.tu-chemnitz.de.
Can you please try whether this problem persists with current Rawhide packages
(namely xsane-0.97) and report back? Thanks.
Yes, it does.
Can you please check whether this problem persists with current xsane-0.99?
Sorry I can't help more, but I don't have access to your hardware.
I can no longer duplicate the problem with what's currently in Raw hide.
