I wouldn’t, I’ve seen this bug myself and it shouldn’t happen. It’s not a minor bug as you can’t do anything with Blender. The trouble is that when I checked it out, there seemed to be no obvious solution to it, the crash log I found gave no indication what was going on. I actually saw it happen on someone else’s computer and at first Blender worked fine but then after a day or two, anything chosen from the file menu like save as or export would just crash Blender.
I copied the version of Blender from my computer, which was working and it worked fine for a few hours and then it started doing the same thing. It’s a bad bug because it seems hard to reproduce. There was a report saying Blender would crash if you tried to export to a long pathname but this seemed like it might have been a different issue as the filename bug caused a crash after the dialog. This crash happens before it right?
I would submit a bug report because this is serious and it needs to be fixed. The person I showed Blender to was almost put off using it completely because of it and had to go back to Maya to get his work done.
Try downloading another copy of Blender and see if you get the same problems. If you do, can you post a crash log and also have you done any particular action that may have started it crashing. For example, the person I knew that had his crashes imported .obj models from Maya.
