Simple Scan crashes on starting

mmmm_cake · 2014-09-14 17:41:09

I have been using Simple Scan for some time now with no problems. This morning it was working perfectly. Then I rebooted my computer, and now when I open Simple Scan, an empty window opens and immediately closes. I can't figure out what's going wrong, especially because the application doesn't seem to open at all when I try to start it from a terminal. I have already tried uninstalling and reinstalling it to no effect. I would try deleting any data it has stored on my computer, but I don't know where it is or whether that even exists. Anyone have any ideas?

More information: Now I can run Simple Scan from the terminal and when it crashes it returns "Segmentation fault (core dumped)". The application seems to run fine when I start it as root (sudo simple-scan), but it doesn't list my scanner under the available sources. Could there be some permissions error?

Bumping despite age because this is almost my exact problem, but only surfaced in the past week. I run the openbox window manager, and don't get the empty window which closes quickly (I don't get any window at all, just the gnome working spinner for several seconds)

I've never had to run simple-scan as root, and I really, really would prefer not to start doing so. That said, running as root I can scan successfully.

To re-hash the above, I receive the Segmentation fault (core dumped) message when trying to run from terminal.

Similar problem here. simple-scan debug mode does not provide useful details beyond the seg fault.
`scanimage -L` reports that my Brother MFC-J6270DW offers 2 scanning devices, brother4:net1;dev0 and brother4:net1;dev1.
simple-scan defaults to dev1 and crashes. If I configure it to use dev0 instead, everything works fine!
scanimage works for both devices.

dmesg returns this:

scan-thread[10567]: segfault at 3ec ip 00007f9ed6e7c147 sp 00007f9ed778d9b0 error 4 in libsane-brother4.so.1.0.7[7f9ed6e67000+25000]

libsane-brother4.so.1.0.7 belongs to brscan4, the driver from Brother:

I've reported my issue upstream: https://bugs.launchpad.net/simple-scan/+bug/1499710
