commit 23f401d5e015ebfb283df1a86e82540c1507083d Author: Isis Lovecruft isis@torproject.org Date: Tue Nov 5 06:00:48 2013 +0000

Catch potential KeyErrors on bridge ID lookups in bridgedb.Main.

We should catch the KeyError here, as sometimes this loop gets a bridge ID from an extra-info descriptor and tries to lookup the bridge, causing a KeyError on the lookup.

* ADD try/except wrapper to catch KeyErrors on looking up bridges by ID in the bridges dict in bridgedb.Main.load(). --- lib/bridgedb/Main.py | 17 +++++++++++------ 1 file changed, 11 insertions(+), 6 deletions(-)
