[SOLVED] Dropbox refusing to start

I upgraded from dropbox-3.8.8 to 3.16 (from AUR) and now dropbox refuses to start:

$ dropbox
Traceback (most recent call last):
  File "dropbox/__init__.py", line 9, in <module>
  File "dropbox/overrides.py", line 494, in <module>
  File "dropbox/overrides.py", line 396, in __ssl_wrap_socket_internal_ca_certs
  File "dropbox/ssl/revoked_certs.py", line 11, in <module>
  File "dropbox/legacy_crypto/__init__.py", line 10, in <module>
  File "dropbox/legacy_crypto/pyca.py", line 5, in <module>
  File "cryptography/hazmat/backends/openssl/__init__.py", line 7, in <module>
  File "cryptography/hazmat/backends/openssl/backend.py", line 28, in <module>
  File "cryptography/hazmat/backends/openssl/cmac.py", line 12, in <module>
  File "cryptography/hazmat/primitives/constant_time.py", line 9, in <module>
AttributeError: 'module' object has no attribute '_init_cffi_1_0_external_module'

I also tried to install dropbox-3.14.7 which produces the exact same output and problem.
I suspect a python-related problem and tried to re-install python and python2 without success. I am clueless where to start looking for the cause of this...
Can anyone help me to get dropbox running again?

Re: [SOLVED] Dropbox refusing to start

I think this goes to package comments in AUR so the maintainer can help you.

Re: [SOLVED] Dropbox refusing to start

I was able to fix the problem myself, but am not exactly sure what caused it in the first place.
By comparing the files in the package and the actually existing files in /opt/dropbox I noticed more files being present in the system than what should be there. Especially some libs were present twice with differing version numbers.
So the steps to solve the problem and make dropbox work are as simple as

# pacman -R dropbox
# rm -rf /opt/dropbox
# pacman -U dropbox-3.16.1-...tar.xz

I don't know why the old files (I guess from 3.8 or maybe even earlier) where still present in the system or were not removed while upgrading dropbox, but at least it's working again.
