Description psychonaut 2010-10-15 12:35:18 UTC Calc crashes whenever the user attempts to open a spreadsheet
with a nonstandard filename extension, or without a filename extension.  This
problem occurs quite often when opening a spreadsheet which has been dynamically
generated and named by a web server.  For example, the popular MicroStrategy web
application lets users download dynamically generated HTML and Excel
spreadsheets, but it doesn't give these resources a filename extension.

Reproducibility: Always

Steps to reproduce:
1. Take an Excel (.xls) or HTML (.html) spreadsheet, and rename it to remove the
filename extension, or give it a nonstandard extension (such as .foo)
2. Use Calc to open the renamed file.  This can be done by via
the command line (e.g., "/usr/bin/oocalc") or by File->Open
and selecting it with the file selection dialog.

Observed behaviour:
3. The Document Recovery pops up to say, "Due to an unexpected
error, crashed..."

Expected behaviour:
3. Calc should have successfully opened the file.

I think this problem may be unique to Calc.  I'm not able to reproduce the
problem in Writer.

You may test this procedure in Open Office version 4.01 Rev. 1524958 on your files, as it seems this issue has been remedied. Tested on this build and Calc can open files regardless of invalid file extensions or lack of extension.

foo file (originally xls) opens OK.
