Package: twinkle
Version: 1:1.1-2+b2
Severity: important
Twinkle crashed when I pressed the Close button of the log window. I
had just done "Select All" and "Copy" from the context menu of the log
window.
The console output was as follows:
*** glibc detected *** twinkle: corrupted double-linked list: 0x0000000000df0e10 ***
