Sansa Clip+ 8GB,
Somewhere between a 486K and 635K comment the Clip+ locks up. This
appears to be related to total comment size rather than individual
tags. In the following xxpc refers to the image size, 2x and 3x
indicate multiple METADATA_BLOCK_PICTURE entries.
729K 3x30pcsize - crash *
635K 50pcsize - crash
486K 2x30pcsize - okay
480K 45pcsize - okay
* crash occurs whether or not replaygain is enabled, this is the only
one I've tested that for.
In the case of crashes the player freezes, holding down the down
button is required to turn it off. It then takes longer than normal to
start up again, seems to do a reset to an earlier state. Total file
size was 4.5M (3x30pc), 4.4M (50pc), 4.2M (45pc/2x30pc). I used the
Hydrate-Kenny_Beltrey.ogg file for testing.
