Reporting this issue in the hopes that enough information will accumulate to positively identify a bug. This has happened on one site of two that we recently upgraded from D5 to D6. Unfortunately, I can't provide a definite path to reproduce the problem.
We will have more D5-D6 upgrades during the fall. If I find information that can help to reproduce this issue, I'll add it to this report.
Subsequent to a D5 to D6 upgrade (and corresponding IMCE upgrade from 5.x-1.3 to 6.x-2.0-rc1), all IMCE user profile roles contain incorrect data. The settings after the upgrade were as follows:
|Permitted file extensions||665x720|
|Maximum image resolution||1|
|Maximum number of files per operation|
The values should have been (and prior to the upgrade were):
|Permitted file extensions||gif png jpg jpeg txt doc pdf tif psd xls ppt mp3 mp4 wav odt odp ods docx pptx xlsx|
|Maximum image resolution||665x720|
|Maximum number of files per operation||1|
As you can see, the field values are correct, but assigned to the wrong fields! As I mentioned above, this has happened only on one site of two we've recently upgraded, but it's not unlike this reported bug: User number settings scrambled after upgrade from Drupal 5.x to Drupal 6.
