.DCL files and pk3 fun - can't find image for the shader

[KungF00]

Compile my map and archive appropriate files into a pk3.

Drop the pk3 in /mainta, run the map and everything is fine.

pushmenu decals, restart the map and the decals are there. Cool. Save and exit (new dcl file is written to mainta/maps/dm)

Updated my pk3 with the new .DCL file.

Now the map crashes every time I try to load it. If I remove the .DCL file everything runs fine.

Qconsole.log says it can't find image for the shader.
