Comment 3 for bug 191094

I had the same problem with aptitude:

97% [Waiting for headers] [Waiting for headers] [Waiting for headers] [Waiting for headers] [Waiting for headers] [Waiting for headers] [Waiting for headers] [Waiting for headers] [Waiting for headers] 188B/s 0s*** glibc detected *** aptitude: double free or corruption (out): 0x0a728cc8 ***
======= Backtrace: =========
/lib/tls/i686/cmov/libc.so.6[0xb79c6604]
/lib/tls/i686/cmov/libc.so.6(cfree+0x96)[0xb79c85b6]

And it was because of I had two monitors at the same time, and the terminal was as wide as both of them, afer I resized the terminal to normal (only in one monitor) I was able to finish the update successfully.
