Bug#39717: Switch header/source doesn't work with .c files, it searches for a nonexisting .cpp

[greatfinger at hotmail.com]

Package: kdevelop
Version: 2.1beta (using KDE 2.2.2 )
Severity: normal
Installed from:    Mandrake Linux 8.2 i586 - 8.2
Compiler:          gcc version 2.96 20000731 (Mandrake Linux 8.2 2.96-0.76mdk)
OS:                Linux (i686) release 2.4.18-6mdk
OS/Compiler notes: 

I started a workspace in KDevelop, a .c console
program completely empty. I inserted files I'm
working on (they where already made) and I tried
to use the Header/Source switch function (from the 
right-click menu anywhere in the code), and switchinf
from the source to header is ok, but trying to
switch back to source corde tells me it doesn't
find "Source.cpp" file. Yeah, I know, it's a .c
file, .cpp file simply doesn't exist. That's it.
