af filter with -af channels=2:2:1:1:1:0 is freezing on some files

On some mp4 (ie not all of them), the channel merge (right channel copied to the left one) is failing:
mencoder -msglevel all=9 -af channels=2:2:1:1:1:0 -ovc copy -oac faac $SOURCE -o $DEST

The process freezes always at the same stage (50%) but I had various experiences with other files. The CPU usage is 100 %.

I am using mencoder 1.0~rc4+svn20111024-0.0 from Debian multimedia. I also tested with the one in Debian (1.0~rc4.dfsg1+svn33713-5) which fails the same way.

The gdb bracktrace is the following:
