Could be used in UVMM, we received a traceback:
File "/usr/lib/pymodules/python2.6/univention/management/console/modules/uvmm/uvmmd.py",
line 84, in request
raise UVMM_Error(str(ex))
UVMM_Error: Could not open socket "/var/run/uvmm.socket": 2

In UCS 3.2 we introduced a traceback reporting tool. Problem is that the tracebacks are not very meaningful. Sometimes they cannot: A meaningful traceback may expose confidential data, e.g. failed LDAP queries. As tracebacks give really weak test experience, it might be useful to add another mechanism for selected code regions: A new UMC_Error that presents a dialogue to the user with a slightly improved layout: "The command %s failed. The following steps may help to solve the problem: * Updates are available. Install them first. * %s * %s If the error persists, hints about the cause can be found in the following log files: * %s * %s The following sections in the online documentation and the support database cover %s: * %s * %s If you have a maintenance contract with Univention, you can also contact the support, otherwise you may ask in the forum or send the traceback (along with the log files) to Univention." Advantage: Feels better (we present solutions); does not look too technical and broken, more like "correct error handling" of a known issue. Disadvantage: Hides the prominent "Send traceback" which may reduce feedback rate. Maybe a possible solution (e.g. a restart of the service) really works: We will never know of the initial problem (which may affect several more people).
