APE decoder bug? Random loud noise

[gomger]

Been using rockbox since some days on my sandisk clip+, and I am having problems playing APE files.
The files are encoded using "high" setting, and during the playback sometimes semi-randomly I get only loud noise and no music.
Because sometimes when i reverse 10 seconds, and replay the "damaged part" I get the exact same problem.
While in other times, in same file, it suddenly works fine. (perhaps it depends how much i reverse..)

Seems like a bug in the APE decoder to me, or might there be some other cause/solution?
Thanks for any help.

Either a decoder bug or corrupt file.  Probably worth copying the file off the player and seeing if it decodes correctly on the PC.
