Title:
pygtk's pangocairo module crashes pydoc search
Status in “pygtk” package in Ubuntu:
Confirmed
Bug description:
Ubuntu 12.04, 64bit
Python crashes every time I run "pydoc -k $something", which should
search all installed modules to find keywords from the doc strings.
Eg:
$ pydoc -k subprocess
subprocess - subprocess - Subprocesses with accessible I/O streams
** (python2.7:22364): CRITICAL **: pyg_register_boxed: assertion `boxed_type
!= 0' failed
zsh: segmentation fault (core dumped) pydoc -k subprocess
If I strace it, I see that the last python module read is pygtk:
open("/usr/lib/python2.7/dist-packages/gtk-2.0/atk.so", O_RDONLY) = 11
open("/usr/lib/python2.7/dist-packages/gtk-2.0/atk.so", O_RDONLY|O_CLOEXEC) =
12
open("./pangocairo.so", O_RDONLY) = -1 ENOENT (No such file or
directory)
...
open("/usr/lib/python2.7/dist-packages/gtk-2.0/pangocairo.so",
O_RDONLY|O_CLOEXEC) = 12
** (python2.7:22008): CRITICAL **: pyg_register_boxed: assertion `boxed_type
!= 0' failed
