Is this still an issue with recent releases?

[Ben Andersen (ben72)]

I will try to check tomorrow. Thank you for asking.

[Michael Nagel (nailor)]

this does not seem to be hardware-related. but just to be sure: while you are at it, please try if using xsane works. thanks!

[Ben Andersen (ben72)]

I tried now and got the exakt same result, simple-scan crashes. It works to scan with xsane. Even though I got an i/o error at first. I then started hplip to have a look at the printer setup. Then xsane worked.

What does the title "Crash when starting to scan (floating point error) ", especially the part with floating point error mean? I can find no reference in the report...

[Ben Andersen (ben72)]

It's the error output in the terminal when running the program and trying to scan.

I cannot find any reference to said error output. Please post it here. Thanks!

The error message is in english:

$ simple-scan

(simple-scan:3645): GdkPixbuf-CRITICAL **: IA__gdk_pixbuf_new: assertion `width > 0' failed

** (simple-scan:3645): CRITICAL **: page_set_scan_area: assertion `page->priv->image != NULL' failed

Are you running Ubuntu? Can you try to catch the bug with apport? After doing what you did to get xsane working, does simple-scan work then, too?

[Ben Andersen (ben72)]

I'll try next time I'm in the office. I run Ubuntu 10.04.3.

[Ben Andersen (ben72)]

Ok, I reported it using apport here:
https://bugs.launchpad.net/ubuntu/+source/simple-scan/+bug/923087

It always works to scan using xsane and never in simple-scan. It doesn't matter if I use Xsane first.
