xsane crashes during scanner search

Hello,

After upgarding my arch installation yesterday I encountered problem with xsane - it crashes with segfault in librsvg.

It goes like this: I type xsane into terminal, it displays little popup with info 'scanning for devices' and then crashes with Segmentation fault (core dumped),
from syslog I got this:

[24100.373813] xsane[16817]: segfault at 1 ip 00007f71da54082b sp 00007ffe5785f350 error 4 in librsvg-2.so.2.44.14[7f71da4e6000+322000]

It worked fine some time ago (I haven't used scanner for a while), neither xsane nor librsvg was upgraded recently - first thing I wanted to try was downgrading xsane or librsvg but I have no older versions in pacman cache.
xsane 0.999-3 was built Mon 17 Sep 2018 11:43:59 PM CEST
and librsvg 2:2.44.14+1+g17bb3cd6-1 on Thu 30 May 2019 04:26:52 PM CEST
Scanner and xsane worked fine last month, maybe some other package screwed something I'm not aware of.

I have epson L3050 printer/scanner connected through network, I can scan normally using utsushi so scanner works.

Anybody experienced this recently?

Use gdb to get a stack trace, https://wiki.archlinux.org/index.php/De … _the_trace and cross-check the involved libs w/ your pacman log (on what was updated)
Did you maybe change your gtk theme/icons?

Thanks for reply,

I did gdb trace: https://pastebin.com/22Q2Rf2i

Yes I changed my gtk theme to Mojave Light with Papirus icons - I doubt this has something to do with crash, because if I run xsane like this:

GTK_THEME=Adwaita:light xsane

it crashes just as before.

If I remove utsushi from dll.conf (sane config file), xsane starts up just fine but does not detect my scanner anymore.

This comes out of gtk_widget_render_icon() so it's pretty much certainly a corrupt icon file (and/or a bug in librsvg)
=> Undo the theme/icon changes; I'm not even sure that GTK_THEME works for gtk2 this way (it doesn't here, no impact on the used theme)

kowal256 · 2019-08-01 13:31:52

OK, it IS the theme, xsane works if I remove .gtkrc-2.0.

It works launched like this:

env GTK2_RC_FILES=/usr/share/themes/Default/gtk-2.0-key/gtkrc xsane

It seems that this theme is indeed incompatible with gtk2, Other gtk apps (all of them using gtk3) work just fine.
I will create alias to command above and use xsane without theme.

Thanks for help
