FS#12693 - Error accessing playlist control file after USB connection
Current developer build (2012-06-10), on Sansa Clip Zip
While audio is playing, connecting USB and disconnecting it again causes a splash with message “Error accessing playlist control file”. Sometimes followed by a hard crash (like undefined instruction).
Initial analysis shows that the problem occurs in playlist.c:get_filename. An lseek in the playlist control file fails. This lseek fails because the file descriptor (fd) was closed during USB connection. On receiving a SYS_USB_CONNECTED event in apps/misc.c, function system_flush() calls playlist_shutdown().
So the playlist subsystem seems to have been de-initialised during USB connect, but not completely, causing problems when the playlist subsystem resumes during USB disconnect.
This is reproducible on the simulator.
