Most probably, but we need more data about the cause(s), so until you or someone else reproduces the problem and provides the additional data, I don't see how we can make any progress. Your build was stripped of debug symbols, so we don't even know in which source line the crash happened, and cannot make any intelligent guesses why that could happen. Another important detail is the font that was being opened at the point of the crash. So if you or someone else can provide these details, I'm sure we will find the culprit soon enough. It could even be that this is already solved in the development sources. Thanks.
