Bug concerning acciaccatura and \time?

[Thomas Ruedas]

Hi,
please consider the code snippet below, which is part of a larger piece. 
It compiles without errors on my machine, but the output is incorrect in 
that it produces the time signature 1/4 twice in the second bar, namely 
first correctly at the beginning of the bar but also after the acciaccatura.
I have similar passages which are typeset correctly, so I think it may 
be a bug.
