1.9.4 displays button text inline with event text in sidebar widget hover popup

Just upgraded ai1ec to 1.9.4 “free” version from 1.9.3 “free” version.
Issue one of several critical event display bugs from this upgrade:

When viewing the event listing page, the sidebar widget hover/popup text now shows all button text inline with event info (even if buttons are turned off). For example hover/popup text now shows “Back to Calendar When: February 26, 2013 @ 9:00 am – 5:00 pm Add to Calendar Add to Google Where: Advocates for Youth…”

Sidebar widget hover/popup text is correct on pages other than event listing page.
