User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.6) Gecko/20040206 Firefox/0.8 Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.6) Gecko/20040206 Firefox/0.8 I renamed a folder and used the "/" character as part of the new name. The new name is displayed with the "/" showing in the pane, but all the mails in the folder disappear. Any more attempt to rename the folder fails with the following message in a pop-up window. "The folder could not be renamed. Perhaps the folder is being reparsed, or the new name is not a valid folder name." However, when I closed and restart Thunderbird the original name without the "/" character reappeared together with the "missing" mails in the folder. Reproducible: Always Steps to Reproduce: 1. Rename a folder and use the character "/" as part of the new name 2. The folder name changes in the pane and the mails in the folder disappear 3. Attempt to rename the folder and remove the "/" and you will get the error message I mentioned above. 4. Restart Thunderbird Actual Results: The old name of the folder (before I renamed it with "/" as part of the new name) reappears; the missing mails in the folder reappear. Expected Results: If "/" is an invalid character in a folder name; it ought not to apparently allow a new name, nor should the mails in the folder seem to disappear. A pop-up with an error message that so-and-so characters are invalid characters in a folder name is more appropriate.
