I added some debugging output to the DateTime class to create stacktrace when a DateTime is assigned whose `m_dt` field is a `nullptr`.
The following is the stack trace when this happens: ./indicator-datetime-service(_ZN5unity9indicator8datetime8DateTimeaSERKS2_+0x45)[0x55abe5d8ba6f] ./indicator-datetime-service(_ZN5unity9indicator8datetime9EdsEngine4Impl15get_appointmentEP11_ECalClientRSt10shared_ptrI13_GCancellableEP14_ECalComponentP10_GTimeZone+0x1c4)[0x55abe5d9210f] ./indicator-datetime-service(_ZN5unity9indicator8datetime9EdsEngine4Impl20add_event_to_subtaskEP14_ECalComponentPNS3_13ClientSubtaskEP10_GTimeZone+0x9c)[0x55abe5d92ce3] ./indicator-datetime-service(_ZN5unity9indicator8datetime9EdsEngine4Impl24on_event_fetch_list_doneEPv+0x21c)[0x55abe5d9171f] ./indicator-datetime-service(_ZN5unity9indicator8datetime9EdsEngine4Impl24fetch_detached_instancesEP8_GObjectP13_GAsyncResultPv+0xe5)[0x55abe5d91221] ./indicator-datetime-service(_ZN5unity9indicator8datetime9EdsEngine4Impl29on_event_generated_list_readyEPv+0x26)[0x55abe5d9131f] /lib/x86_64-linux-gnu/libecal-2.0.so.1(+0x25d85)[0x7f2834aedd85] /lib/x86_64-linux-gnu/libecal-2.0.so.1(+0x2d204)[0x7f2834af5204] /lib/x86_64-linux-gnu/libgio-2.0.so.0(g_simple_async_result_complete+0x86)[0x7f28346405c6] /lib/x86_64-linux-gnu/libgio-2.0.so.0(+0xa068f)[0x7f283464068f] /lib/x86_64-linux-gnu/libglib-2.0.so.0(g_main_context_dispatch+0x14e)[0x7f2834468e8e] /lib/x86_64-linux-gnu/libglib-2.0.so.0(+0x52240)[0x7f2834469240] /lib/x86_64-linux-gnu/libglib-2.0.so.0(g_main_loop_run+0x83)[0x7f2834469533] ./indicator-datetime-service(main+0x59b)[0x55abe5d5dffb] /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xf3)[0x7f28340450b3] ./indicator-datetime-service(_start+0x2e)[0x55abe5d5ccee] -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to indicator-datetime in Ubuntu. https://bugs.launchpad.net/bugs/1891740 Title: Indicator Applet Crashes with unity::indicator::datetime::DateTime::get() const: assertion failed: (m_dt) Status in indicator-datetime package in Ubuntu: New Bug description: # Problem When the calendar is synced to a Google calendar that contains "task" entries, the indicator applet crashes.
