Depends on the sort of game and the sort of technical issues. If the AI is bad like "doesn't do anything" bad, then it can't come back around to "fun". But if the AI is bad like "aliies charge straight forwards then run around in circles and do a dance in front of enemies" then it kinda can be fun. As for glitches, if it's graphical glitches or glitches with ragdoll physics it can often make a game more oddly fun.
But if the game is trying to play itself off really seriously, then it just collapses and I feel sorry for it. If it's a game like Saints Row 2 that's ridiculous when it's working right, then it makes it a lot more fun and whacky.
