Submitted with commit ae31e2303e948a3e05f1f7cd7d32972f8d22e6c5 by Elvis Angelaccio to branch master.


Repository: kio


Description
-------

This patch is an attempt to fix this ugly error message: http://i.imgur.com/26Y6Xix.png
The problem is that in KIO::buildErrorString() the ERR_CANNOT_LAUNCH_PROCESS case assumes that the `errorText` starts with the name of a process (example usage in [kio_smb](https://lxr.kde.org/source/kde/kdenetwork/kio-extras/smb/kio_smb_mount.cpp#0110)). However, Slave::createSlave() also uses ERR_CANNOT_LAUNCH_PROCESS but with "self-contained" error messages, which results in the unfortunate screenshot above.

There is no easy way to fix this without breaking the error messages from the client slaves, so I propose to add a new error code ERR_CANNOT_CREATE_SLAVE which is used only by Slave::createSlave() (at least for now).
