sane and scanimage crash in Feisty but not in 6.06

[CrawfordBest]

Binary package hint: libsane

scanimage (root or user) gives "segmentation fault (core dumped)"

After I click Acquire Scan in Xsane it closes.

Xsane says my Scanner is Hauppage WinTV!

When I change the configuration file (?) to Epson V750 and save it it doesn't stay but comes back as Hauppage.

I am using a firewire interface card and cord.

This setup worked in 6.06 but after I upgraded to 7.04 it didn't work anymore.

Thanks for your bug report. Please try to obtain a backtrace <http://wiki.ubuntu.com/DebuggingProgramCrash> <https://wiki.ubuntu.com/Backtrace>and attach the file to the bug report,a valgrind would also be perfect <https://wiki.ubuntu.com/Valgrind>. This will greatly help us in tracking down your problem.

Does this help? So it is there. I tried sane-find-scanner in the past
(6.04 ?) and don't remember that it showed up. I will try to change
permissions but I don't know why scanimage is only finding the
hauppage. I saw somewhere that the Epson V750 (aka GT9000) IS supported.

Thanks.

It looks like I may have wasted your time. Sorry. See below:

After changing permissions on /dev/sg7 I got this:

So sane substituted the hauppage for the scanner in Xsane. Strange. It
is a PCI card which has Composite, S-video, and audio RCA inputs,
certainly not Firewire or SCSI.

Is this (copied from the above lines) something you are interested in?

Sorry I'm not specialised in scanners. Finally this is still segfaulting or not ? Thank you

[CrawfordBest (cbestsf)]

No segfaults. I had to set permissions again this morning on /dev/sg7
though. I hope I don't have to do that every day!

Thanks again.
