Please describe the problem:
I have the standard Raw Image Data (raw) plug-in installed. When I normally run GIMP, the plug-in is undetected, i.e. you cannot see it in File->Open/File->Save dialog.

However, everything works properly (for only one time) after GIMP queries the plug-ins when you remove the pluginrc file.

Steps to reproduce:
1. Check if the plug-in is detected: (i) Run GIMP (ii) File->Open (iii) Select File Type (iv) Check if the Raw Image Data plug-in is on the list (v) Close GIMP - the plug-in is not detected.
2. Remove your pluginrc file.
3. Same as 1. - it is detected.
4, Same as 1. - it isn't detected.
5. Repeat 1. multiple times...  - it is never detected.

Remember to restart GIMP every time.

Does this happen every time?
Yes.

Other information:
Procedure Browser always shows file_raw_load and file_raw_save procedures.

If you change your pluginrc file from:
(plug-in-def "/usr/lib/gimp/2.0/plug-ins/raw" 1171581633
    (proc-def "file_raw_save" 1
[...]
        (icon stock-id -1 "")
         ""
[...]
    (proc-def "file_raw_load" 1
[...]
        (icon stock-id -1 "")
         ""

to:
(plug-in-def "/usr/lib/gimp/2.0/plug-ins/raw" 1171581633
    (proc-def "file_raw_save" 1
[...]
        (icon stock-id -1 "")
         "raw"
[...]
    (proc-def "file_raw_load" 1
[...]
        (icon stock-id -1 "")
         "raw"

the plug-in always will be detected.
