Hello All, This is exercisable in Dillo 3.0.4.1, but not new. I found it by accident in my hack-up of Dillo 3.0.4. The reproduction is: - enable cookies for .google.com - navigate to https://mail.google.com/mail/?ui=html - fight the links until you get a screen with two fields, one for the username and one for the password - type something into the username field - select it and drag to the password field -- core dump I am on: - OSX 10.6.8 - Dillo 3.0.4.1 with SSL enabled - FLTK 1.3.3 - with dpid, etc from Dillo 3.0.4 with extensive hacking so the fault could be Mac-specific. Essentially the same fault (in Fl::dnd()) is reproducible in clean Dillo 3.0.4, with FLTK 1.3.2, clean dpid, etc, so I *think* it's not a product of my hackery. Clean Dillo 3.0.4 does not report the CGContextSetShouldAntialias and related errors, so I *think* that they are unrelated. Some errors and backtrace below. So far, I have not reproduced this fault in the FLTK input test program. Does anyone have a favourite piece of form html for me to try, to see if we can get out of needing gmail for the reproduction.
