Appending to a nsFileSpec via the += operand does not work for more than a filename. Here is a code snippet: // initalPath is some real directory nsFileSpec fileSpec(initalPath); fileSpec += "nested/file.txt"; At this point fileSpec does NOT equal the expected initialPath plus "nested/ file.txt". In the diff that I send you John, I have included a testcase that will reproduce this problem. This problem does not exist for windows, and pretty sure it does not for Unix.

Set milestone to M5. John, should you fix this for M5?

This is blocking dougt a little, but I am not sure whether he requires it before M5. I was planning to fix it for M5, but is it required? Doug?

This is not *required* for m5.

Doug Turner says he doesn't need this until M6.

Changing to P1 the priority of bugs upon whose solution others are waiting.

FIx checked in. Assigning dougt as qa contact.

Bulk moving to XPCOM, in preparation for removal of XP File Handling component. (XPFH has received two bugs in ~5 months, and is no longer in active use.)
