Thanks for your report. I cannot reproduce and your report does not give much information. Can you please tell us:

* Your project profile (for example 1920x1080 25fps)
* What kind of clip in the Library you were trying to use ? Was it created with a different project profile (for example in a 30fps project)? If you right click on the Library clip, at the end of the menu you have "Open containing folder" that should open a file manager pointing to the library clip. This is a xml file with an .mlt extension. Could you copy it to a .txt file and attach it here ? (it will contain paths and file names so if you don't want to share this you can replace them with xxx in a text editor)
* What exact operation are you performing that causes the crash: clicking on the library button "Add clip to project", dragging library item in the project Bin, or in Timeline ?
