One of the urgent bugs in RoundCube 0.3-stable is that from time to time the body text does not appear. This means that empty e-mails can be received. It seams that this happens mostly, when e-mails have been sent with Hotmail. I expect that this bug will be solved, when RoundCube 0.3.1 will be released. For now, you can use this patch to solve the problem. Instruction: 1) Make a backup of the file program/include/rcube_imap.php, which is in your RoundCube directory. 2) Open the original program/include/rcube_imap.php file. 3) ADD the extra lines (see attachment) between: line 1138 $structure = iml_GetRawStructureArray($structure_str); and line 1139 $struct = false; After that save the file.
