It turns out that with 7.50.1, curl changed their provider of
internationalized domain name support from libidn to libidn2, which we
don't have a package for yet.
You can see the change in this standalone patch for CVE-2016-8625:
https://curl.haxx.se/docs/adv_20161102K.html
And here Daniel Stenberg, the curl maintainer, recommends we simply
disable IDN support for the time being, since the fix is incomplete:
https://curl.haxx.se/mail/lib-2016-11/0033.html
This is already the case; here is an excerpt from the build log:
------
2797 checking whether to enable Windows native IDN (Windows native builds only)... no
2798 checking whether to build with libidn2... (assumed) yes
2799 checking for pkg-config... (cached) /gnu/store/9z40bkd8q9s8krjkhqysrn262gwsww4p-pkg-config-0.29/bin/pkg-config
2800 checking for libidn2 options with pkg-config... no
2801 configure: IDN_LIBS: "-lidn2"
2802 configure: IDN_LDFLAGS: ""
2803 configure: IDN_CPPFLAGS: ""
2804 configure: IDN_DIR: ""
2805 checking if idn2_lookup_ul can be linked... no
2806 checking idn2.h usability... no
2807 checking idn2.h presence... no
2808 checking for idn2.h... no
2809 configure: WARNING: Cannot find libraries for IDN support: IDN disabled
[...]
3309 IDN support: no (--with-{libidn2,winidn})
------
I hope this doesn't break the interface with any packages referring to
the new curl with a graft.
