+    There are differences in the .rodata section of the binary.
+    .
+    The following analysis was done on the binary currently in sid, not the one
+    built by tests.r-b.org (because I couldn't figure out the download URL of
+    the latter).
+    .
+    The first difference is at address 0x0033bd3d:

+    (There seems to be some pattern to the differences, e.g., "va" becomes "n^".)
+    .
+    There's nothing relevant in the symbol table:
+    .
+    % objdump -j .rodata -TswC sqlitebrowser | vipe
+    000000000032e050  w   DO .rodata        0000000000000013  Base        typeinfo name for ForeignKeyEditor
+    0000000000409d28  w   DO .rodata        000000000000000e  Base        typeinfo name for CharCommand
+    .
+    (Note the size is 13.)
+    .
+    Looking at the complete dump (s/-j .rodata/-D/), the only reference to the
+    address range of the first difference (/(0|\<)344a/) is here:
+    .
+    000000000022d170 <qInitResources_translations()@@Base>:
+      22d170:	48 83 ec 08          	sub    $0x8,%rsp
+      22d174:	48 8d 0d 05 7c 11 00 	lea    0x117c05(%rip),%rcx        # 344d80 <typeinfo name for ForeignKeyEditor@@Base+0x16d30>
+      22d17b:	48 8d 15 7e 7a 11 00 	lea    0x117a7e(%rip),%rdx        # 344c00 <typeinfo name for ForeignKeyEditor@@Base+0x16bb0>
+      22d182:	bf 02 00 00 00       	mov    $0x2,%edi
+      22d187:	48 8d 35 f2 78 11 00 	lea    0x1178f2(%rip),%rsi        # 344a80 <typeinfo name for ForeignKeyEditor@@Base+0x16a30>
+      22d18e:	e8 cd ad e8 ff       	callq  b7f60 <qRegisterResourceData(int, unsigned char const*, unsigned char const*, unsigned char const*)@plt>
+      22d193:	b8 01 00 00 00       	mov    $0x1,%eax
+      22d198:	48 83 c4 08          	add    $0x8,%rsp
+      22d19c:	c3                   	retq   
+      22d19d:	0f 1f 00             	nopl   (%rax)
+    .
+    I would like to chase down the C++ source code of this to see whether the
+    object at 0x1178f2(%rip) (344a80) is long enough that the differences
+    belong to it.  That function is presumably generated by a call to
+    Q_INIT_RESOURCE(translations) somewhere:
+    .
+    qtbase-opensource-src-5.12.5+dfsg/src/corelib/global/qglobal.h:388:#define Q_INIT_RESOURCE(name) \
+    qtbase-opensource-src-5.12.5+dfsg/src/corelib/global/qglobal.h:389:    do { extern int QT_MANGLE_NAMESPACE(qInitResources_ ## name) ();       \
+    qtbase-opensource-src-5.12.5+dfsg/src/corelib/global/qglobal.h:390:        QT_MANGLE_NAMESPACE(qInitResources_ ## name) (); } while (false)
+    .
+    However, I don't see anything relevant in uses of /\<translations\>/ in
+    sqlitebrowser, and looking for «Q_INIT_RESOURCE(translations)» in
+    codesearch.debian.net has four matches in three packages, none of them
+    obviously relevant (kid3, flightgear, clementine).
