Opening files via "Open as administrator" generates commandline with extra blank space

[Siva Chandran P]

Binary package hint: nautilus-gksu

Suppose if we open an archive(i.e. .tar.gz) via "Open as administrator" then it opens two file-roller window. One window says "Unable to open" and other window shows the archive content. But the first window steals focus, so we have to click "Ok" and close it to do anything with the other window.

Internally nautilus-gksu finds the application name for selected file's mime type. But the returned application name contains one extra blank space which leads to a commandline something like "appBBvfspath", where app is application name, B is a blank space and vfspath is a vfs path of the file. In my case file-roller treats the second blank space as seperate parameter and tries to open it.

This not only happens with file-roller but with lot of other applications(even with nautilus itself BUG #79110) too.

The patch I have attached strips any leading/trailing spaces from the commandline(cmd).

This is a noncritical bug which does not meet the SRU guidelines. I can be talked into a hardy SRU, since we are more generous there due to LTS-ness.

Hardy fix uploaded, thank you!

Accepted into hardy-proposed, please test and give feedback here. Please see https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

[Ansus (neptunia)]

I use it under Intrepid and works well.

I have reproduced the error under the version of nautilus-gksu in hardy-updates, 2.0.0-5ubuntu3, and have verified that the version in hardy-proposed, 2.0.0-5ubuntu3.8.04.1, fixes the issue. I verified that it works properly even in the case of a filename that begins with a space. I also verified that gksu and gksudo continued to function as expected.
