This might be related to Bug 17397 where any mp2+cue file would crash the scanner (reported as fixed in 7.6.1 33072 nightly and assigned to Andy Grundman).

Testing done with 7.6.1 33072 with the Music Folder only containing one cue file and one mp2 file. All scans were "Clear library and rescan everything". Mp2 files without a cue file play without a problem.

In all cases the files played without any difficulty in SBS 7.5.4 and prior (I have never run 7.5.5).

Simple cue file with 1 or 2 tracks
----------------------------------
Scanning works fine with no errors in scanner log.
Library statistics show as expected.
But, when trying to play from Web Control, it seems to play (with the time incremented as normal) but there is no sound.
Clicking pause sometimes restarts play from beginning of track.
server.log has *hundreds* of identical entries, e.g.:

[11-08-13 13:23:14.0812] Slim::Networking::IO::Select::__ANON__ (147) Error: Select task failed calling Slim::Web::HTTP::sendStreamingResponse: Invalid frame offset 583522 for frame 4236 (69a81c8a) at /<C:\PROGRA~2\SQUEEZ~1\server\SQUEEZ~3.EXE>Slim/Player/Protocols/File.pm line 250.
; fh=Slim::Web::HTTP::ClientConn=GLOB(0x793790c)


Straightforward cue file with 3 or more tracks
----------------------------------------------
Scanning works fine with no errors in scanner log.
Library statistics show as expected.
But no response at all in Web Control when trying to play
SBS stops running
Server.log has the entres:

[11-08-13 13:36:05.5302] Slim::Utils::Misc::msg (1236) Warning: [13:36:05.5300] Error: Unable to read at least 10 bytes from file.
