[texhax] Very long author name is not braking into two lines ...

[Petar Milin]

Hello ALL!
Sorry for being pushy, but I must try again to get some/any answer for 
my problem.
I am using Tetex under Ubuntu 6.06. In particular article I am writing, 
I use:
\usepackage[longnamesfirst]{natbib}
\bibliographystyle{apalike}
Then, I use \citep{} or \citet{} etc.
The problem is that one reference (with three coauthors) contains very 
long name of the first author. It has not been broken into the next 
line, but almost fell of the paper. Does anyone know how to fix that? 
Although second and third authors are not named (et al. has been put), 
the first one is making problem, having four string of letters in his 
family name. One way to fix that is not to use \citet{}, but plain text. 
However, I wonder if it is possible to fix that within natbib.
Hence, in the text where I use citep{Somebody della Something von 
Somewhere:etal:2007}, the name of the fist author is very long and is 
not braking in the next line. Please, how to fix that?

Best,
PM
