Bug#948339: thunar: Thunar crashes when selecting or clickin on webp image

[jEsuSdA <listas@jesusda.com>]

Package: thunar
Version: 1.8.11-1
Severity: important

Dear Maintainer,

I've been working with webp-pixbuf-loader for a while and it works fine.

https://github.com/aruiz/webp-pixbuf-loader/

It brings webp image support to all GTK apps like ristretto, eye of mate,
geeqie, etc.

I updated recently the Thunar file manager to 1.8.11 (from official Debian
testing repositories).

In previous version of thunar works fine, but in this version thunar crashes
when clicking a webp image o even when selecting one.

This is the error message:

(thunar:7316): GdkPixbuf-CRITICAL **: 14:58:52.249:
gdk_pixbuf_calculate_rowstride: assertion 'width > 0' failed

(thunar:7316): GdkPixbuf-CRITICAL **: 14:58:52.249: gdk_pixbuf_get_rowstride:
assertion 'GDK_IS_PIXBUF (pixbuf)' failed

(thunar:7316): GdkPixbuf-CRITICAL **: 14:58:52.249:
gdk_pixbuf_get_pixels_with_length: assertion 'GDK_IS_PIXBUF (pixbuf)' failed
Segmentation fault


I discovered that it is caused by

"misc-image-size-in-statusbar = TRUE"

If I set this value to FALSE, Thunar works fine. This is a workaround but I'm
graphical designer and web developer and "misc-image-size-in-statusbar=TRUE" is
very useful to me.

The point is that it works fine in previous Thunar version, so, maybe something
has been broken in new Thunar releases.

I hope you could solve this problem or maybe tell me how I can solve by myself.


Thanks a lot!
