"bzr mv" is case insensitive

My repository contains many files that only differ in case, recently I tried to change the naming scheme but "bzr mv" complained.
Bzr version is 2.0.0
Below are the steps I took:

1. initial "bzr st ." is empty
2. I run
bzr mv ./sol_=bAABAbaB.groovy sol_bAABAbaB.groovy
bzr mv ./sol_=bAABABaB.groovy sol_bAABABaB.groovy

note, that the only difference is in the end: baB vs BaB
first instruction succeeds, the second complains:

bzr: ERROR: Could not move sol_=bAABABaB.groovy => sol_bAABAbaB.groovy: solutions/aaa-bb-abab/5/sol_bAABAbaB.groovy is already versioned.

Note, that the target name is incorrect in the error message

3. "bzr st ." shows
renamed:
 solutions/aaa-bb-abab/5/sol_=bAABAbaB.groovy => solutions/aaa-bb-abab/5/sol_bAABAbaB.groovy

here the target name is correct

I could reproduce this with bzr.dev (r4732)
