People spending all their time fixing broken libraries that they would have been quicker writing themselves is a problem that pretty much never happens, there are multiple ways in which to determine if a library is likely stable or mature enough to be used, and testing whether it works or not is usually a fraction of the time that it would take to write the thing from scratch.

If you open source some code without making any grandiose promises and someone somehow ends up in the position where they are wasting their time fixing it, its entirely their own decision / fault.
