Photo thumbnails issue : X10 mini (India), ver 2.1

[#1]

Photo Thumbnails (in ALBUM) do Not load completely.

Did the below 2 trials, but could not resolve the issue
- Unmounted & Mounted the SD card
- Restarted the phone

Could this be due to Faulty upgrade using Update Services?

Please suggest a fix.

Appreciate your help/guidance.
