Import-Function buggy in Version 5.2 ?

Hello all,

after upgrading from version 5.1 to 5.2 I'm encountering problems with
the import of data from a file. My programs still run under version 5.1
but show a different behaviour in version 5.2.


Here is the way it works in version 5.1:

In[]:Import["ex_values.dat","Table"]

Out[]:{{2.5,-35.8919,0,0,180},{-2.5,-35.8919,0,0,180},{7.5,-35.8919,0,0,180},{-7.5,-35.8919,0,0,180},{12.5,-35.8919,0,0,180},{-12.5,-35.8919,0,0,180},{17.5,-35.8919,0,0,180},
....

Everything is fine, Mathematica imports a list of lists, or a matrix if
you like it that way.


Here is what happens with version 5.2 (same data-file)

In[]:Import["ex_values.dat","Table"]

Out[]:{{2.5,-35.8919,0,0,180},{-2.5,-35.8919,0,0,180,7.5,-35.8919,0,0,180,-7.5,-35.8919,0,0,180,12.5,-35.8919,0,0,180,-12.5,-35.8919,0,0,180,17.5,-35.8919,0,0,180,
......

The first entry is correct (see above), but the 6'th to n'th value are
just members of one big list.

Anybody knows what's going on here, is this a bug in version 5.2 ?
(I would be able find a workaround to get things running again, but
this is not the point here)


Thanks for your help !

Stefan
