simple-scan crashed with SIGSEGV in g_thread_create_proxy()

[Brian Murray]

Binary package hint: simple-scan

I had scanned a document as text and then went on to scan again but this time as a photo when simple-scan crashed. My scanner is actually connected to another system and I'm using sane to connect to it. Here are some messages from the server's syslog file:

I had to end up unplugging the scanner's usb cable and replugging it in to get this working again.

Does this still occur in simple-scan 0.9.4?

[Brian Murray (brian-murray)]

I tested it with 0.9.5-1ubuntu1 and it did not crash. Thanks!
