Sorry, if this bug is a duplicate, but I couldn't recognize a really similarity to older bugs.

As I wasn't using scim-bridge "actively", I just describe what I did:
I simply tab-jumped through Rhythmbox Music Player when the crash alert popped up. This can be reproduced by pressing tab in Rhythmbox about 10 times, but does not occur everytime.

Since this is the output I get when I try to restart SCIM after a (possibly unprovoked? = I was using the google-chrome-unstable Browser in an unrelated matter at the time) sudden crash of scim-bridge, the bug I encountered may be related to this one.
