file-roller crashed with SIGSEGV in strlen()

Binary package hint: file-roller

I was deleting a file in .xpi (ff extension) archive and adding a substitute file in its place. The archive in question was mr tech local install .xpi file. I'm a novice at deletion & addition so there is possibility that something didn't add up. Hence had to try to do that procedure As it became obvious that it was not working then closed the program (or so I thought) and opened Xarchiver. While I sucessfully did that there I got a message stating that Archive Manager had crashed.
