If I put

My weird string x:"<x" is the most simplified form I could come up with of some text that was causing the above error on my trav v0.10.4.

Resolution: fixed
Status: newclosed

Fixed in r7205 for 0.11, r7207 for 0.10.5 and r7211 for 0.12.

I set the milestone of this ticket to 0.10.5, as one can then assume that it's fixed in later versions.

Again, many thanks for reporting this issue!
