Thanks for reporting. i have fixed this in git. Just some notes.

• r2 0.9 is old. try to report bugs is they can be reproduced from the code in git.
• armthumb plugin does not exists. use rasm2 -a arm -b 16
• the arm and arm-thumb assemblers are pretty incomplete, feel free to contribute if you notice some missing opcodes.
