Do Your .DMG Files Mount Properly with Snow Leopard?

CNET reports a problem affecting several Mac users: .dmg files do not mount with Snow Leopard. This is a serious problem as this is a rather standard and heavily used format for AMc OS X. There is currently no solution to fix this bug, even though deleting some preferences might temporary solve the issue:
Said files are: "com.apple.frameworks.diskimages.uiagent" and "com.apple.diskimages.fsck" located in Preferences folder of the Library of your user account (home). It seems to be required to reboot the computer after erasing them. As it does not affect most or all users, this bug might well be associated with the installation of a specific application, and unless it is identified as belonging to Apple Apps, this problem will most likely take time to be fixed.
