Description
It seems to me I found a case when the algorithm for the automatic spectral line search goes into an infinite loop somewhere. It probably requires a very rare sequence of fluxes in the spectrum because it is the first time I've seen something like this despite a frequent use of the code for Methanol Multibeam project. I will examine the issue a bit further and attempt to fix it.

Indeed a problem was found inside STLineFinder::getMask method. It was clearly a bug which revealed itself if there was a large number of narrow lines. Typically this happened with a low threshold and spectral averaging on. The problem has been fixed now (in r1497).
