Not a bug, but a function of your current locale.  For more details, see FAQ E9 in the bash FAQ:
http://tiswww.case.edu/php/chet/bash/FAQ

Either set LC_ALL=C in your environment (technically, LC_COLLATE=C is sufficient, but then you have to guarantee that LC_CTYPE is compatible), or use [[:upper:]] and [[:lower:]] instead of [A-Z] and [a-z] for proper locale case-sensitive regexes in your current locale.

In the following list of files:

test.Jpeg
test.MPEG
test.JPEG
test.Mpeg
test.mpg
test.MPG
test.jpg
test.JPG

I want to find any files with an extension containing uppercases (the point is to then rename them to lowercase).

This works :
find . -regex '.*\.[ABCDEFGHIJKLMNOPQRSTUVWZYZ][a-Z]+$'
find . -regex '.*\.[JM][a-Z]+$'

This returns all of the files, including those who do not have upper cases in them :
find . -regex '.*\.[A-Z][a-Z]+$'

Therefore I believe [A-Z] and [a-z] do not work as they are supposed to.
