BPM scan fails on uppercase extension (OS X)

[delta]

I had this problem that Mixxx would sometimes scan a track and get a result of 0 BPM no matter what (both in 0.11 and my own builds of 0.12, but I have not made one of those in a while so I don't know if it got fixed already). I finally tracked this down to... the file extension. When it was .mp3 everything worked correctly, but the files in question had an extension of .MP3. I assume something gets lost between file system and Mixxx' internal database.

This is on Mac OS X 10.9 (but I think the problem existed before 10.9, can't say for certain though), running a Journaled HFS+ file system.

Oh I forgot to add: When I rename the files to lowercase, they get detected as new files and scan correctly.

Another addendum: It seems that this actually got worse in my build of 0.12, because there renaming the file does NOT change anything. Both 0.11 and 0.12 still show an uppercase extension in the "Properties" window, but only 0.11 seems to be able to deal with the rename properly.

Confirmed on OSX 10.8.5 (HFS+ journaled) , renaming a track to uppercase extension can make BPM detection and beatgrid generation fail.

Tested:
AIFF->pass
WAV->pass
OGG->pass
MP3->fail
M4A->fail
AAC (wont load at all)

I don't think this is polish -- not being able to scan tracks on mac is a pretty big problem, and given libraries_from_hell I can imagine this coming up a decent amount of the time.

Mixxx 2.1.0-beta1 (build 2.1 r6543), macOS 10.13.3

LOSSLESS.M4A -> pass
.AIF -> pass
.FLAC -> pass
.M4A -> pass
.OGG -> pass
.WAV -> pass
