This issue was reported to Quality Engineering and has been fixed in Notes 6.5.5 and Notes 7.0.

Excerpt from the Lotus Notes and Domino Release 6.5.5 MR fix list (available at

SPR# JDOG678MCA - Launching attachments which have double exclamation marks (!!) in the filename causes a Notes client crash. The double exclamation mark characters are not allowed in a filename. With this fix, when we encounter such a situation, a valid filename will be created instead.

Refer to the Upgrade Central site for details on upgrading Notes/Domino.

A cumulative client hotfix (CCH) is available for Notes Client 6.5.4 that fixes the issue reported in SPR# JDOG678MCA. Since hotfixes do not receive the extensive testing that maintenance releases and fix packs do, customers are encouraged to implement workarounds or deploy a release containing the fix. However, if workarounds are not possible or applicable and you still need a fix, contact IBM Technical Support to request the CCH containing the fix for this issue.
