Hi! After being bitten by this bug I have now found the exact way to reproduce it (for me). If the cursor is located on the tab-bar (which is quite normal if you just switched the urxvt tab) you can't produce some characters like ~ and `. If you move the cursor down into the «normal» area these character can be produced again.
