Yes. Indeed.

Here's the problem. My version uses
\def\Telefon{\mvchr{84}}
which overrides g-brief's definition silently, while \newcommand results in an
error, if the macro is already defined.[1]
I guess this has been done by default, in order to "inform" the user that a
file definition is overridden.
The easiest fix is probably to replace the \newcommand by \def. This keeps the
Symbol available in principle (for other apllications).

[1] The procedure goes as follows:
1. gbrief defines \Telefon
2. then gbrief loads marvosym, which defines \Telefon as well
3. right after that, g-brief defines \Telefon again
The error happens in step 2.
