Package: calibre
Version: 2.55.0+dfsg-1
Severity: normal
When Calibre first starts, it throws two exceptions, but continues
loading and works correctly. They appear practically as the same time
as the Calibre splash screen. The exceptions are:
Traceback (most recent call last):

Failed to create system tray icon, your desktop environment probably does not
support the StatusNotifier spec
Now, this works when I launch Calibre from my WM itself (I run i3 with
i3bar; I copied this exception from .xsession-errors), or if I run it
from a terminal and have it open. However, if I launch it backgrounded
from a terminal and exit the terminal process before the exception is
displayed, I get a window titled "ERROR: Startup error", with the
text "There was an error during calibre startup. Parts of calibre may
not function. Click Show details to learn more".
If I click the "Copy to clipboard" button, I get the exact same
exception I reproduced here. If I click on the "Show details" button,
I get the following text:

File "/usr/lib/python2.7/traceback.py", line 13, in _print
file.write(str+terminator)
IOError: [Errno 5] Input/output error
Then, Calibre keeps running, but does not start a UI; I have to
manually kill it in order to get it started again.
Note that I don't believe this bug to be related to #657730, as the
exception categories are quite different.
