Bug#307089: sane: resolution slider failure on amd64 also
reassign 307089 libsane-extras retitle 307089: libsane-extras: [epkowa] uses a resolution range when scanner doesn't support it thanks Mark Nipper [EMAIL PROTECTED] wrote: Hi Mark, David, However, it still segfaults when trying to move the resolution slider. Attached the output using SANE_DEBUG_EPKOWA=255. This problem has been diagnosed as a bug in the epkowa backend, which always reports a resolution range even when the scanner supports only a fixed list of resolutions. This only happens for a precise type of scanners. No ETA for the fix, but it shouldn't take long, hopefully. Could you have a look to the advanced options, and see if you have an option like show a list of resolutions ? I saw something like that in the advanced options of my 2480, maybe it could be used as a workaround until the fix. As for the original bug report, the bug seen with the epson backend is just not possible; the epson backend always reports a list of resolutions.

Mark Nipper [EMAIL PROTECTED] wrote: Hell, I'll arrange shell access if you think it would help any. I should note here that I've successfully used just scanimage from the command line and alternate resolutions do work, so it's purely something related to the GUI code here. But I'm sure you already knew that! Just thought I'd mention it. I tried to reproduce the bug with my Epson 2480, only to realize that the 2480 uses a list of resolutions and not the resolution slider. I've contacted the epkowa maintainer, but he has a release to get out the door asap and has no time allocated for debugging :( Does scanimage also segfault if you specify an unsupported resolution ? If you could get scanimage to segfault, *that* backtrace could help a lot more than the xscanimage backtrace. I think the backend goes nuts on unsupported resolutions, but that's just a very wild guess right now. (so forget me if it ends up being something totally different ;) I wish I had more hardware available to do tests :/ JB. -- Julien BLACHE [EMAIL PROTECTED] | Debian, because code matters more Debian GNU/Linux Developer| http://www.debian.org Public key available on http://www.jblache.org - KeyID: F5D6 5169 GPG Fingerprint : 935A 79F1 C8B3 3521 FD62 7CC7 CD61 4FD7 F5D6 5169 -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Let me Well, there's a list of supported resolution before that, and 312 isn't in that list. That's a (very) wild guess, and I don't see how it could cause GTK errors. know if you want me to try out whatever you come up with first or if you need me to build a new package with the most recent backend or some such. I'll try to build the new package ASAP.

It's a full backtrace so I'm just attaching a separate file of that. Hmm, thanks, but as long as their are only GTK functions in the backtrace, I really can't make sense out of it :/ Could you run the epkowa backend with debugging (SANE_DEBUG_EPKOWA=255) and send the output ?

Guess I'll have to give a try to the epkowa backend for the Epson 2480 I own and see what happens, because the backtrace won't help :/ Just tried the epson backend. Any reason the epkowa uses a slider instead of a drop down like the epson backend? The Well, the backend is free to choose :) epson drop down worked without any segfaulting of course, although I didn't actually try scanning with it. OK. Could you give a try to the test backend ? It uses a slider too, and it doesn't segfault here, I'm not even getting a GTK warning. If it works for you with the test backend, then the bug is in the backend. I'll try to update the epkowa backend to the latest version in the upcoming days, maybe it'll fix this problem...

Mark Nipper [EMAIL PROTECTED] wrote: I'm having a similar problem on amd64. I tried checking my gtk-theme with gtk-theme-switch2 (since I have no idea how to check it otherwise as I'm simply running sawfish and I had to install the gtk-theme-switch package just to get that) and it was set at Default. But I didn't have any of the gtk[2]-engines-* packages installed either until I installed gtk-engines-pixmap and gtk2-engines-pixbuf at the behest of gtk-theme-switch. I'm using the epkowa backend currently if it matters. Ah, epkowa. so it's a little different from the original report as I don't ever get a gtk_widget_event failure and mine just segfaults quickly afterward.
