librsvg 2.41.0 in [testing] makes ibus-chewing unusable. During the startup, ibus-chewing tries to load its SVG icon to the notification area. librsvg 2.40.16 can render it correctly, while 2.41.0 just crashes with SIGSEGV.

Upstream report:

Additional info:
librsvg 2:2.41.0-1
ibus-chewing 1.5.1-1

Steps to reproduce:
1. gdb /usr/lib/ibus/ibus-engine-chewing
2. ibus-daemon -r -v
3. Switch to ibus-chewing (Chinese - Chewing in ibus status icon)

Now ibus-engine-chewing crashes with a probability of ~80%.
