[davidp at ruthenium:/tmp/case]$ shopt | grep case
nocaseglob      off
nocasematch     off

They look to be likely suspects :)

[davidp at ruthenium:/tmp/case]$ touch foo FOO bar BAR

[davidp at ruthenium:/tmp/case]$ ls [A-Z]*
[davidp at ruthenium:/tmp/case]$ shopt -s nocaseglob
[davidp at ruthenium:/tmp/case]$ ls [A-Z]*
BAR  FOO  bar  foo


a shopt -u nocaseglob ought to fix it.

(Does Ubuntu have that set by default??)
