FS#12404 - r31037 crashes device and sim after leaving FM Radio and resuming playback

r31037 and later causes the device and sim to crash when resuming playback after leaving FM Radio. This crash has been reproduced on both e200v1 device and w32 sim and the e200v2 w32 sim. The failure is less likely to happen when there is a small number of files on the device/sim. (I have approximately 2200 files on the device and 5400 on the sim).

Tested with r30145

Steps to reproduce:
1. load the attached fms file (needs 35-Nimbus.fnt)
2. load an fm preset file - be sure to have station art
3. enter fm radio and select a preset station be sure art is displayed
4. power off device or sim
5. power on device or sim
6. start a playlist
7. stop playback
8. power off device or sim
9. power on device or sim
10. enter radio
11. exit radio
12. select resume playback
13. device or sim crashes

The e200v1 crash is:
Data abort
at 000095F0 (0)

This appears to be a problem with the radio art. Entering fm radio on a station without art and exiting and then resuming playback does not crash. Entering fm radio on a station without art and then selecting a station with art will cause a crash when exiting and then resuming playback.

I was able to get the linux sim to fail. This is the gdb output:
