Can you please update to xterm-286-1.fc17 and see if the problem persist? I don't think that will change (it's recent but no rework was done). In a quick check here, I don't see it breaking. However the new code (which is being exercised) could break if the event did not pass the xterm-widget but rather some other widget. In other places I guarded against that by calling getXtermWidget() rather than casting the value. The report does not show the X resource settings; given the traceback it seems that the alternateScroll resource would be set. If the widget is not really xterm, then the associated screen pointer would be invalid (whether or not the alternateScroll resource was set). It would be nice to have the X resource settings (and some clue of the user's interactions with xterm) to see which path led to this. However, adding a guard inside AlternateScroll() would not change xterm's behavior since there is already one in AmountToScroll() which is used in each of the callers. I don't think there is enough information here for me to reproduce the problem. I can reproduce the problem at will by placing the mouse over the scroll bar and scrolling up using the scroll wheel. Works every time. Note that scrolling using the mouse wheel in the text area works fine, only scrolling up using the scroll wheel in the scroll bar produces the problem. The difference (if any) between the two is that the action within the scrollback is added using XtAugmentTranslations. A long time ago (say more than ten years ago) there were some systems which didn't work well with that (seems they had some tablesize limit?). But I'm not seeing the same problem with the Fedora package for xterm in Fedora18 - so I'm still stuck. Clicking up/down and dragging all work - here. Don't click or drag. Both of those actions work for me too. Just place the mouse pointer over the scrollbar and use the scrollwheel. If you want i can post details of my hardware configuration... I did that, too. But Matthieu Herrb's followup to me indicating your additional traceback, etc, got me to notice the attachment in comment #4 and realize that getXtermWidget() is needed in this case.
