(I had first only seen the other loops, which looked pretty harmless)
Though i had assumed that the non-const iterator would have detached the list anyway.</pre>

This is similar to the change ... just for more cases. If the API was
used with ::checkStartup it could happen that an item got removed from
the startups while iterating the list of startups. Thus the data
corrupted resulting in a crash when getting a similar crash.
In this case the code now uses erase instead of remove to have a valid
iterator.
