Bug 1331190 - Log viewer sometimes doesn't load the log (#2083)

Occasionally the log viewer doesn't seem to load. The JS error in the
console was `q.lineNumber.split is not a function`. This was happening
because `q.lineNumber` was sometimes interpreted as a number. To fix
that, the use of `toString()` is used before splitting it.
