Details

(Keywords: assertion) 

STEPS TO REPRODUCE
1. load http://www.mozilla.org/editor/midasdemo/
2. create a bulleted list like so:
     * 123
     * 456
3. select the text "2345"
4. type BACKSPACE

ACTUAL RESULT
###!!! ASSERTION: JoinNode called with a non-text left node!: '0', file editor/txtsvc/src/nsTextServicesDocument.cpp, line 2603

EXPECTED RESULT
One list item with the text "16" (OK), no assertion

PLATFORMS AND BUILDS TESTED
Bug occurs in Firefox mozilla-central on Linux

ADDITIONAL INFORMATION
It's NOT a regression from bug 157546, fwiw.
test_backspace_delete.xul triggers the same assertion for me, FWIW.  I have not bothered to figure out what it is trying to do in detail, but the backtrace makes it sound like deletion of selection is involved:
